Foundation packages represent the most direct path to increased power while retaining drivability and safety. The combination of Dinan modifications work harmoniously with one another and offer a balanced blend of enhanced engine efficiency, improved acceleration and increased power to go along with a tasteful high-performance look and unmistakable Dinan sound. Whether you start with the base Foundation package that includes the core hardware building blocks (intake and exhaust), or opt for packages that further enhance your vehicles power output and abilities you will be well on your way to an elevated experience. WHY GET A PACKAGE? We understand the building a modified car in stages is often preferred for various reasons. Not knowing how deep into the modification journey you may go or simply for financial reasons are common justifications for a measured approach. However, often when building in stages, parts are mixed and matched that were not designed to interact with one another which can lead to sub-par results and unhappiness with a vehicle you should be enjoying. By purchasing and installing popular curated packages of parts that were all designed to work with one another you bypass these common faults and receive a complete solution you can enjoy to the fullest from day one. As a bonus, a 10% discount is applied to package purchases compared to buying the same components a la carte. WHAT'S INCLUDED IN THE BASE G8x M3/M4 FOUNDATION PACKAGE (F)? Dinan Carbon Fiber Cold Air Intake (D760-0063) for increased flow, efficiency as well as underhood visual appeal Dinan Free Flow Axle-Back Exhaust w/ Black Tips (D660-0093-BLK) and corresponding X-Pipe (D660-0094) for maximum aural pleasure Features: Maximum gains of +6 HP and +5 lb-ft of torque (Exhaust) Smoother, louder and sportier sound (Exhaust + X-Pipe) Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions (Exhaust) Deletes resonators between the secondary catalysts and rear muffler for increased volume (X-Pipe) 11-pounds lighter than the stock (Stock: 66-pounds vs. Dinan: 55-pounds) (Exhaust + X-Pipe) Reduced intake restriction for Increased turbo efficiency with greater power potential on modified builds (Intake) More robust and aggressive induction soundtrack (Intake) Improved throttle response (Intake) 7 points towards the illustrious Dinan deck lid badge

Looking to elevate the acoustics of your X3 M40i / X4 M40i with an exhaust system that not only offers a much-improved sound while retaining the flexibility associated with valves, but also raises the eye appeal beyond the mundane? Look no further than the Dinan valved cat-back to meet all your needs… and then some!

The full cat-back requires no cutting and utilizes factory mounting locations that allow the Dinan exhaust system to be a straightforward and painless install. Fabricated from brushed 100% T304 stainless steel, TIG welded, and free of hydroformed pipe, the upgraded system is also a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. The most glaring change being the replacement of the OEM dual slip tips in favor of an M-inspired quad tip configuration. Despite the limited room, Dinan was determined to offer four individually functioning pathways/tips and not lessen the representation with Y-tips or other gimmickry. The result is a proper quad setup furnished with cavity covering 3.75-inch (95mm) tips in either black ceramic or polished stainless ensuring the system can be appreciated even before it is heard.

While looks are important, the auditory advantages are what any enthusiast is truly after with an exhaust system, and the Dinan offering for the G01/G02 M40i platform delivers in spades. For not only aural enhancement via the elimination of the central collector/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer-flowing single pipe system. This pathway feeds into a Helmholtz-equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM’s) to rowdy when in it (high RPM’s), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed, however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle. No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.

Features:

Maximum gains of +6 HP and +5 lb-ft of torque

Enjoyably louder, sportier sound w/ a delightful octave drop

Drone abatement technologies used to reduce cabin resonance

Quad 3.75-inch (95mm) double-walled, polished (or black ceramic coated) clamp-on tips with laser engraved Dinan logo

Larger diameter piping for increased flow (83mm vs. 80mm)

Factory resonator/collector removed for increased volume

7-pounds lighter than the stock system (60-pounds vs. Dinan: 53-pounds)

100% 304 Stainless Steel construction

Factory valve functionality retained; refined or rowdy from the same exhaust

Direct bolt-on w/ no cutting or welding required

Factory-like fitment with included mounting hardware and valve componentry for both pre-LCI and LCI compatibility

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. For weight savings and simplicity, the stock single to dual pipe setup has been abandoned in favor of an enlarged, free flowing single pipe system. This pathway feeds into a muffler that limits frequencies associated with drone, as well as assists 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 cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice. Features: Maximum gains of +6 HP and +5 ft-lb of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4.5-inch (114.3mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (83mm throughout primary run vs. 80mm at largest point) Factory resonator/collector removed for increased volume 10-pounds lighter than the stock system (Stock: 56-pounds vs. Dinan: 46-pounds) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware

Dinan sport mufflers are designed to compliment the M3 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" black ceramic 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.

Features of the F9X M3 Dinan Exhaust -

Single channel design
Sportier Sound
10 lbs lighter than stock part + 100% 304 stainless steel construction
Simple installation using high quality BMW OEM clamps and hangers
Quad 3" laser engraved black ceramic coated exhaust tips with Dinan logo
6 HP & 5 lb-ft of torque
"Straight Through" canister design
Helmholtz chamber to remove drone

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.

Whether you start with the base Foundation package that includes the core hardware building blocks (intake and exhaust), or opt for packages that further enhance your vehicles power output and abilities you will be well on your way to an elevated experience. WHY GET A PACKAGE? We understand the building a modified car in stages is often preferred for various reasons. Not knowing how deep into the modification journey you may go or simply for financial reasons are common justifications for a measured approach. However, often when building in stages, parts are mixed and matched that were not designed to interact with one another which can lead to sub-par results and unhappiness with a vehicle you should be enjoying. By purchasing and installing popular curated packages of parts that were all designed to work with one another you bypass these common faults and receive a complete solution you can enjoy to the fullest from day one. As a bonus, a 10% discount is applied to package purchases compared to buying the same components a la carte. WHAT'S INCLUDED IN THE BASE G87 M2 FOUNDATION PACKAGE (F)? Dinan Carbon Fiber Cold Air Intake (D760-0063) for increased flow, efficiency as well as underhood visual appeal Dinan Free Flow Axle-Back Exhaust w/ Black Tips (D660-0100-BLK) and corresponding X-Pipe (D660-0101) for maximum aural pleasure Features: Maximum gains of +6 HP and +5 lb-ft of torque (Exhaust) Smoother, louder and sportier sound (Exhaust + X-Pipe) Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions (Exhaust) Deletes resonators between the secondary catalysts and rear muffler for increased volume (X-Pipe) 11-pounds lighter than the stock (Stock: 66-pounds vs. Dinan: 55-pounds) (Exhaust + X-Pipe) Reduced intake restriction for Increased turbo efficiency with greater power potential on modified builds (Intake) More robust and aggressive induction soundtrack (Intake) Improved throttle response (Intake) 7 points towards the illustrious Dinan deck lid badge

Looking to elevate the acoustics of your X3 M40i / X4 M40i with an exhaust system that not only offers a much-improved sound while retaining the flexibility associated with valves, but also raises the eye appeal beyond the mundane? Look no further than the Dinan valved cat-back to meet all your needs… and then some!

The full cat-back requires no cutting and utilizes factory mounting locations that allow the Dinan exhaust system to be a straightforward and painless install. Fabricated from brushed 100% T304 stainless steel, TIG welded, and free of hydroformed pipe, the upgraded system is also a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. The most glaring change being the replacement of the OEM dual slip tips in favor of an M-inspired quad tip configuration. Despite the limited room, Dinan was determined to offer four individually functioning pathways/tips and not lessen the representation with Y-tips or other gimmickry. The result is a proper quad setup furnished with cavity covering 3.75-inch (95mm) tips in either black ceramic or polished stainless ensuring the system can be appreciated even before it is heard.

While looks are important, the auditory advantages are what any enthusiast is truly after with an exhaust system, and the Dinan offering for the G01/G02 M40i platform delivers in spades. For not only aural enhancement via the elimination of the central collector/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer-flowing single pipe system. This pathway feeds into a Helmholtz-equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM’s) to rowdy when in it (high RPM’s), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed, however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle. No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.

Features:

Maximum gains of +6 HP and +5 lb-ft of torque

Enjoyably louder, sportier sound w/ a delightful octave drop

Drone abatement technologies used to reduce cabin resonance

Quad 3.75-inch (95mm) double-walled, polished (or black ceramic coated) clamp-on tips with laser engraved Dinan logo

Larger diameter piping for increased flow (83mm vs. 80mm)

7-pounds lighter than the stock system (60-pounds vs. Dinan: 53-pounds)

100% 304 Stainless Steel construction

Factory valve functionality retained; refined or rowdy from the same exhaust

Direct bolt-on w/ no cutting or welding required

Factory-like fitment with included mounting hardware and valve componentry for both pre-LCI and LCI compatibility
