Dinan sport mufflers are designed to compliment the M5 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Four 3.5" stainless tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This setup is worth 3 point towards your Dinan badge.

The 2 series is the nearest embodiment of legacy BMW ideals in today's lineup. As such, in both the non-M and M trims, the series is continuously lusted after by the enthusiast community. While the G87 M2 may get the lion's share of publicity, the G42 M240i is equally as enticing and offers a robust value proposition for individuals looking to balance performance with comfort. Equipped with the latest B58 engine also found in the M340i and M440i, the M240i has performance covered in spades. Beyond the vaunted engine, the platform also borrows numerous other components from its 3 and 4 series counterparts. As such, it made sense to imbue the latest M240i with the same Dinan exhaust treatment the aforementioned models received and were heralded for -- an economical valved system with quad tips. Quad exhaust tips have been a signature feature of the most powerful letter in the automotive sphere for quite some time. It is a hallmark of the brand that Dinan has long embraced, limiting its own quad tip usage to those M cars that already sported like tip quantity from the factory. That is until the release of the Dinan exhaust systems for the G20 M340i and G22 M440i in 2019 and now extending to the G2 M240i today. While some may scoff at the feature being implemented into a "pseudo-M," the M240i, and the B58 engine platform, are extremely potent and worthy of such a distinction. The factory valance also accommodates the four massive 102mm tips perfectly, further cementing our opinion that the quad tips were destined to be on this performance model. Being numerous and big are not the only selling points to the tips however. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. With systems available with either black ceramic coated or polished clamp-on, and laser engraved exhaust tips, there is a version that is sure to meet your individual aesthetic needs. The use of quad tips also presented some additional challenges and fostered some innovation to the already visually impressive system constructed entirely of TIG welded and brushed T304 stainless steel. Confined to dual tips, the factory system utilizes only one exhaust valve and functions by eliminating the passenger side tip when the valve is closed, siphoning all gases through the muffler and out the driver's side tip for quieter operation. With the introduction of more pipes/tips, this methodology was not practical, or desired. In true Dinan M exhaust fashion, our talented engineering team decided that integrating a second valve to the system would garner the most favorable results in both symmetry and overall sound. The result is a system that incorporates larger 76mm tubing (vs 70mm stock) and allows freer flow through the entirety of the system but specifically to both outer pipes when the enlarged valves are open. The resulting flow and sound mimics an awe-inspiring straight pipe solution with a deeper and meatier tone, a defining element of all Dinan exhausts. In contradiction to the aggressiveness resulting from open valves, when the valves are closed, all gases are forced into the muffler for sound deadening and exit the two inner tips. Regardless of valve position, the intimate nature of the interior is retained so conversation can continue without an excessively loud drone courtesy of numerous drone abatement technologies in the can. With the Dinan exhaust equipped on the M240i you get the best of both worlds; aggressive tone/sound and civility. A combination that is paramount to any M exhaust, and now by virtue of tip count, the M240i as well. Welcome to the illustrious family. Features: More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM Enjoyably louder, sportier sound Quad 4" diameter clamp-on, double-walled, polished and laser engraved exhaust tips 100% 304 stainless steel construction Larger diameter piping for increased flow (76mm vs 70mm) 4 pounds lighter than the stock system Stock exhaust valve actuator reused, and another valve/actuator added to the opposing side promoting even flow regardless of valve position Computer controlled exhaust valves are retained and limit noise during low speed driving and open fully during high-load conditions Twin exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves Factory-like fitment with included mounting hardware

The Dinan Resonator Delete Kit for the F97 X3M and F98 X4M introduces a more aggressive tone and an increase in volume over the stock system. Coupled with the associated Dinan exhaust, the sound is further enhanced into a smoother, fuller and more aggressive note that is befitting of the performance SAV. The offering removes the hydro-formed factory resonated section and replaces it with 70mm T304 stainless steel tubing for freer flowing capabilities. In place of the factory resonator itself, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes, which are commonplace in the market. This sophisticated 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is often present with stock systems.

The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. Utilizing factory cut points and mounting mechanics this Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. Max HP Gain4 @ 6600 RPM - Max Torque (lb-ft) Gain3 @ 6600 RPM Features: Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware

Dinan sport muffler is designed to compliment the M2 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. This muffler can be used on its own for a modest increase in sound or with the Dinan center section for an exotic and thrilling sound. Four 3.5" stainless tips engraved with the Dinan logo fill out the rear valence. Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This setup is worth 3 point towards your Dinan badge.

Unfortunately, the Countryman/X1/X2 is often ignored by the aftermarket despite this popularity and a marketplace that is starving for quality performance parts that the diminutive F56 hatchback enjoys. Enter Dinan, and an exhaust solution that will make any driver envious.

Like its brethren, the M3 and M4, the G87 M2 is a giant leap forward from its predecessor in terms of overall performance and its capabilities. Not surprising given the latter model borrowing heavily from its older siblings' part catalog resulting in a wide swath of components being interchangeable amongst the trio. A few inlet pipe bends prevent the exhaust from being one of those but the M2 is still largely the same as the G8x M3/M4 system. This allowed the extensive drone abatement development applied on those platforms to be used on the G87, fast tracking the R&D process. The result is the introduction of another member of G8x valved axle back exhaust family that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved. It's the perfect marriage for all tastes and allows civility or impassioned aggression depending on what the situation demands. The combination is one Dinan has deemed fitting for the marques signature performance models that cater to the tasteful enthusiast who demand the best for all situations. Visually, the Dinan G87 M2 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust includes massive, quad 4.5-inch (114mm) clamp-on, double-walled, polished stainless steel and laser engraved exhaust tips. Despite the seemingly cartoonish size on paper, the tips mesh seamlessly and fill the factory cut-outs to complete the OEM+ look with a healthy dose of audible attitude. LIMITED AVAILABILITY: Initial release of the Dinan G87 M2 Axle Back exhaust is extremely limited. Further raw material for additional production runs are not expected until late Q3 2023. Features: Maximum gains of +6 HP and +5 lb-ft of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Four, diffuser filling, 4.5-inch (114mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (76mm vs. 70mm) 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds) Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions 100% 304 Stainless Steel construction Factory-like fitment with included mounting hardware

Dinan engineers designed the F22 M240i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

The system is built to exacting specifications to ensure perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm (3.5") polished exhaust tips for a tasteful, high-performance look.

Maximum performance gains are 6 horsepower and 5 ft-lbs of torque.

Benefits of the Dinan Free Flow Exhaust for the F22 M240i:

+ Uses the factory brackets and hangers for a factory-like fitment.
+ Helmholtz chamber to reduce drone.
+ Enjoyably louder, sportier Sound
+ 100% 304 stainless steel construction
+ Twin 89mm (3.5") laser engraved polished exhaust tips

    Dinan engineers designed the F30 340i and F32 440i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

Dinan also incorporates a Helmholtz chamber design that reduces resonance or"drone" at low RPM. The system is built to exacting specifications to ensure the perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm (3.5") polished or ceramic black exhaust tips for a tasteful high-performance look. The factory computer-controlled exhaust valve is eliminated. Features: More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM Helmholtz chamber to reduce drone Enjoyably louder, sportier sound Twin 89mm (3.5") laser engraved, polished or ceramic black exhaust tips 100% 304 stainless steel construction Uses the factory brackets and hangers for a factory-like fitment

    The Dinan sport muffler is designed to compliment the X5M and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Quad 3.5" stainless tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

    For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

    Like its brethren, the M3 and M4, the G87 M2 is a giant leap forward from its predecessor in terms of overall performance and its capabilities. Not surprising given the latter model borrowing heavily from its older siblings' part catalog resulting in a wide swath of components being interchangeable amongst the trio. A few inlet pipe bends prevent the exhaust from being one of those but the M2 is still largely the same as the G8x M3/M4 system. This allowed the extensive drone abatement development applied on those platforms to be used on the G87, fast tracking the R&D process. The result is the introduction of another member of G8x valved axle back exhaust family that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved. It's the perfect marriage for all tastes and allows civility or impassioned aggression depending on what the situation demands. The combination is one Dinan has deemed fitting for the marques signature performance models that cater to the tasteful enthusiast who demand the best for all situations. Visually, the Dinan G87 M2 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust includes massive, quad 4.5-inch (114mm) clamp-on, double-walled, polished stainless steel and laser engraved exhaust tips. Despite the seemingly cartoonish size on paper, the tips mesh seamlessly and fill the factory cut-outs to complete the OEM+ look with a healthy dose of audible attitude. LIMITED AVAILABILITY: Initial release of the Dinan G87 M2 Axle Back exhaust is extremely limited. Further raw material for additional production runs are not expected until late Q3 2023. Features: Maximum gains of +6 HP and +5 lb-ft of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Four, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (76mm vs. 70mm) 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds) Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions 100% 304 Stainless Steel construction Factory-like fitment with included mounting hardware

All in all this axle-back system is a great upgrade to your beloved X5/6M!

    Get that aggressive tone fitting for the M3 and M4! The Dinan High Flow X-pipe for the F80/F82 M3/M4 elicits an aggressive sound that is sure to capture the ear of all bystanders and delivers the aural recognition that all M3/M4 owners deserve. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that harkens back to the Dinan E9x M3 racing middle exhaust. Rightly so, as the same custom 'X' that was used in that application is implemented on the new F8x chassis for that perfect mix of exotic undertones and raw aggression. Unlike a stamped x-pipe that is so common in the marketplace the Dinan 'X' is thoughtfully designed for maximum flow characteristics and by itself is a work of art. The Dinan X-Pipe removes the factory center section after the secondary catalytic converters, including the large resonator. In its place Dinan introduces straight through mandrel bent 2.75" T304 stainless steel tubing and the custom 'X' for better flow, and an improved throaty sound. In addition, the kit comes complete with mounting hardware, OE quality clamps, and flanges, for simplified installation. NOTE: Since a resonator is deleted there is potential for increased cabin noise associated with the Dinan High Flow X-Pipe. Features: Deletes both resonators, between catalyst and rear muffler. Stock hydro-formed 65mm tubing is replaced by 2.75" (70mm) mandrel-bent tubing for free flow. Includes X-pipe crossover made from mandrel bent tubing for minimum restriction, unlike stamped X-pipes 100% 304 stainless steel construction. Bolt-on installation. Includes mounting hardware.

    The F48 X1 and F39 X2 BMW crossovers are, by volume, one of the most successful lines in the BMW brand portfolio. That success capitalizing on those that want the additional cabin space, akin to an SUV, but without the huge sacrifice to fuel economy courtesy of the fuel efficient B48 4-cylinder engine. For a wide swath of the consumers in these vehicles that is enough and all that is desired. However, for a growing segment of the market, there are also those that want even more. Namely performance, and by association, sound, more commonly associated with the sportier B58 6-cylinder engine. From the factory the stock X1/X2 exhaust is largely silent in all modes which is a travesty for any those consumers that fit in the "more" category, but Dinan offers a solution that rights that wrong. The Dinan exhaust system offers a dramatically improved exhaust note that is not only louder but fuller and deeper as well. 70mm piping, free of hydroforming, is used throughout that allows freer flow to traverse the entirety of the system. The tubing is then fed into a streamlined muffler that is typical of all Dinan exhaust design and utilizes absorption technologies designed to improve exhaust flow and reduce back pressure. The combination results in mildly improved power output at the extreme top end of the power band and a great sporty sound complete with pops for additional aural gratification. Factory valve control is also retained to ensure the perfect blend of civility when not pushing the car and a bit of additional character when in it. Regardless of driving style or conditions the system is purposefully engineered to reduce low-RPM drone, so the cabin of the vehicle remains intimate and not drowned in an excessively loud tone. While sound is the primary reason for any exhaust purchase the styling and craftsmanship also play an important role for the discerning buyer. The Dinan X1/X2 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color.

Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position, amongst a marketplace dominated by angle cuts.

    The Dinan X-Pipe Exhaust for the F95 X5M / F96 X6M LCI offers a more aggressive tone and an increased stock system volume while retaining the factory muffler. This X-pipe exhaust removes the hydro-formed factory center section from the secondary catalysts back to the axle back, including both resonators, and replaces it with larger tubing for freer flowing capabilities. In replacement of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes. This hand-made 'X' is not only good-looking but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system.

Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position, amongst a marketplace dominated by angle cuts. The tips masterfully fill up and accentuate upon the factory cut-outs showcasing an extremely aggressive, yet refined, styling that will turn heads even before it is heard. Features: Maximum gain of +5 HP and +4 ft-lb of torque Enjoyably louder, sportier sound Dual 4" (102mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo 100% 304 Stainless Steel Construction Retains factory valve control Bolt-on installation; Includes mounting hardware

    Evoke passion and excitement with the Dinan Valved exhausts for the GR Supra! Conveying the sweet sounds of a deep, rich, euphonious note that are unmistakably Dinan in addition to retaining the flexibility of valves, Dinan exhausts are the epitome of sound without sacrifice. Utilizing factory cut points and mounting mechanics, the Dinan exhaust system is a straightforward install with precision fitment just like you would expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipe, the upgraded system is a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. An enlarged free flowing single pipe system is employed that feeds into a muffler whose job it is to limit frequencies associated with drone, as well as assist in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows shocking versatility in sound levels when paired with features, like valves, often associated with more fanciful alternatives. The unabashedly spartan, yet effective, pipe layout forces gasses to escape from the rear out of massive dual, straight cut, 114.3 mm (4.5-inch) exhaust tips emblazoned with the laser engraved Dinan logo. The tip branding further cementing any lingering doubt that the system visible is something above and beyond stock-- if it was not already apparent by the blissful music permeating from them. Unquestionable enhancements to the overall chorus emitted through the Dinan system transcend all modes making the vehicle a delight to drive and enjoy. However, for those that wish to have options to limit the extraordinary soundtrack for late night or early morning arrivals/departures (or any number of other reasons) factory valve control is retained. This effectively makes the system behave similarly to a straight-pipe system that promotes maximum flow and volume when the valve is open and emit more subdued resonant vocals when the valve is closed, and exhaust gases are wholly redirected through the muffler. It is the perfect blend of civility when not pushing the car or the full spectrum of auditory delight when in it. No matter the situation, the Dinan valved axle-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice. Features: Maximum gains of +4 HP and +3 ft-lb of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4.5-inch (114.3mm) double-walled, polished clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (83mm throughout primary run vs. 75mm at largest point) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware

    For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. This Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer using factory cut points and mounting mechanics. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. Features: Maximum gains of +4 HP and +3 ft-lb of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, polished clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware

    The F60/F54 MINI Countryman/Clubman and BMW X1/X2 may be a utilitarian vehicle designed to accomplish a variety of tasks but it still embodies the pep and nimbleness most commonly associated with the brand. This sporty underpinning coupled with its diverse abilities make it a popular seller, rivaling even the flagship Cooper S. Unfortunately, the Countryman/X1/X2 is often ignored by the aftermarket despite this popularity and a marketplace that is starving for quality performance parts that the diminutive F56 hatchback enjoys. Enter Dinan, and an exhaust solution that will make any driver envious. Features: Maximum gain of +5 HP and +4 ft-lb of torque Enjoyably louder, sportier sound Dual 4" (102mm) double-walled, polished clamp-on tips with laser engraved Dinan logo 100% 304 Stainless Steel Construction Retains factory valve control Bolt-on installation; Includes mounting hardware
