Finally the answer to your E36 exhaust woes! Upgrade from your old, crusty or quiet exhaust that lacks the OOMPH you want to hear when stepping on the gas. Our crew at Turner have been describing this exhaust with words like “symphony” and “hearty” with its smooth and low frequency tone. This is the kind of exhaust we stand outside and listen to as our residential test vehicle rolls out from work heading off in the distance while singing the oh so sweet straight six sound.
Our new E36 cat back is a tribute to the E36 M3 in more ways than one. The exhaust features 90s styling exhaust tips to compliment the sharp yet rudimentary body lines. Just like the E36 our exhaust was designed to be raw, straight to the point, lightweight and timeless.
To accomplish these goals our engineers rev’d up their creativity and went straight to work. Adapting straight to the mid-pipes our engineers transformed the lackluster 2.0” tubing and stepped up to a true-dual 2.5” exhaust with an integrated x-pipe to smooth out the flow and fine tune the exhaust note just how we wanted. Towards the rear of the vehicle you will find a light-weight and perfectly spec’d muffler featuring fabricated sheet metal hangers, slash cut integrated tips and achieves a fine-tuned exhaust note.
We can only hope the community enjoys this exhaust as much as we at Turner enjoy it. As a part of the community, we are excited to offer this awesome exhaust for all to enjoy.
Non-M Fitment:
Although we designed this exhaust specifically for the M3 model we felt it was a shame to rob this exhaust opportunity from the Non-M E36 owners. Face it, every straight six deserves a sweet exhaust. If you or your fellow enthusiasts feel so inclined our exhaust can be fitted to all standard 6 cylinder E36s. ** For non-m E36s you will have to slightly bend the exhaust hangers to get perfect fitment in the non-m rear bumper/diffuser. **
- CLICK HERE - for a sample of just how good your S50 or S52 can sound!
Why the upgrade?
By now your E36 M3 is approaching 30 years of age and you have a few possible exhaust situations:
- One of the options is you still have the factory exhaust and it is at the end of its life, it could be covered in rust and unsightly or packed solid with soot deposits which is not helping the weight, flow or tone of your exhaust.
- A second option is that you have an aftermarket exhaust that you fitted years ago and it is seeing the same fate as the factory muffler just at an expedited rate, the muffler is no longer sounding or performing the same and needs to be swapped out.
- Another probable exhaust situation you could find yourself in is that you have an exhaust fitted on your M3 that you think sounds good and had no intentions of changing it but after seeing and hearing our Axle Back exhaust you find yourself wanting a new look, sound, and sense of enjoyment from driving your E36.

Lightweight performance exhaust for your E46, featuring a valved muffler and controller to change the sound with the click of a button.
When it comes to shopping for exhausts you want to find one that suits your driving style and sound preference. While one part of you wants to have a loud and aggressive sounding exhaust, there is another part of you that knows you don't want to wake up the neighborhood or annoy your significant other. Finally the answer to your dilemma, thanks to our engineers at Turner you no longer need to choose between rowdy and tame. With your new light-weight performance exhaust you have the option to go from tame and tasteful to loud and rowdy.
Our Valved exhaust was designed specifically for your E46 and there are no other options on the market like this. Control the tone and volume of your exhaust with the click of a button. With the valves closed you have a nice low tone and hearty exhaust note. When the valves are open you get complete unrestricted access to sound and power for when your at the track or just in the mood to let it rip.
Our Turner catback features dual 2.0" stainless steel mid-pipes that connect directly to your factory downpipes. Within the mid-pipes is an integrated x pipe for a smooth flowing center section with lower amounts of back pressure which leads to increased performance and a smoother exhaust tone. The 2.0" mid-pipes crossover and flow into a 3" exhaust section and full 3" valved muffler. The muffler features integrated 3" exhaust tips for an aggressive look that fills out your rear diffuser to get the perfect appearance.
Valved exhausts of this caliber can be found on new performance models, super cars and overall cars way above the price ranges of a nice E46. Surprisingly enough some E46's did come with a type of vacuum actuated mufflers which opened and closed the exhaust under certain rpm ranges, unfortunately by now the factory valve is damaged or the muffler no longer actuates. Although the factory valved muffler on E46's were great in theory, there was very little change in tone and was limited by your driving style. Taking notes from the original engineering process from BMW, our engineers revitalized this cool technology and made it better. The final product is a light-weight performance exhaust that features superior valving and show stopping aesthetics!

Still have the factory exhaust fitted to your B58? You don't know what your missing. Free up lost performance with a new full cat-back exhaust complete with factory valve control!
The B58 engine earned the badge "Worlds 10 Best Engines" four times as of 2023. In 2016 the single turbo straight six found its way to the leaderboards for the first time and followed up in 2017, 2019, and 2020 staying on the charts as one of the best engines in the WORLD.
Our new cat-back exhaust is designed to take out restrictions, maximize flow and give your B58 a signature exhaust note that will excite you on every drive. From the factory your vehicle comes equipped with a combination of three mufflers and resonators that do a great job of silencing the exhaust and restricting flow. There is a center muffler(one restriction), rear section resonator(two restrictions) and a bulky muffler(three restrictions!). With all of those stop gates how do you expect to get the maximum performance out of your vehicle, you simply cannot do so. Lucky for our in-house engineers you no longer have to deal with the quiet and limiting factory exhaust.
To create a cat-back exhaust for this incredible engine the changes happen right after the downpipe. We replaced the factory oval pipe with our full 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep flow to a maximum! With smooth mandrel bent transitions our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature B58 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Dual 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

B58 Engine Design:
BMW's first mass produced turbo charged engine, the N54 took the world by storm opening a whole can of worms in the car industry and aftermarket community. A new era of motors were created with the new B58 roughly 9 years after the N54 had been tested and pushed to its limits along with its single turbo companion, the N55. In 2015 the modular engine family was created and the B58 was released into the wild to set a new standard in performance and reliability. Turning back to their roots the B58 engine features a closed-deck engine design similar to the N54 that allows a massive increased in boost pressure capacity and heightened compression ratio. Thought the B58 is similar in weight and size to its predecessor, the new modular engine makes considerably more power right off the rip. With the new block design heat management has been upgraded to reduce the affects of heat cycling to slow the rate of cooling and prevent engine components from failing due to rapid cooling. Just like the N55 the B58 comes fitted with dual vanos, valvetronic and a single twin scroll turbo. Just 8 years experience of this motor we can all agree that the B58 looks like it could be the future of motors to come. This tunable engine has been tested up to 1000hp with the stock block and hosts a platform for the community to break into a whole new class of attainable "supercar killers".

Upgrading the sound:
Our exhaust allows you to turn up the volume and let the B46/B48 boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B48 if you're not going to upgrade the exhaust? Our signature muffler design allows you to transfer the exhaust valve from your factory system directly onto your new Turner system. The Turner exhaust signature muffler design allows for two flow paths that change both tone and volume. With the vehicle in eco or comfort mode, the valves remain closed, with the closed valves the exhaust system allows the gasses to flow through the muffler toning down the volume and giving a more refined exhaust note. While in driving modes sport or sport+ the valve opens and the flow path changes to a "straight flow path" essentially turning into a straight-piped exhaust for the least amount of restriction and the most amount of B48 sound!
How the cat-back is designed:
To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. Turner replaced the factory components with oversized 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep the flow to a maximum! With smooth mandrel bent transitions, this exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is Turner's signature B46/B48 muffler with a beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Dual 3.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

T304 Stainless Steel 12mm barbed exhaust hangers Tig-Welded in OE locations for precise fitment.
Strategically placed slip joints provide the most adjustability to obtain perfect fitment
Optional OBD Plug-In:
The factory-valved muffler is not only controlled by different driving modes like comfort, sport, and sport plus but the RPM also plays into whether the valves are opened or closed. If you are looking for a solution to define whether your exhaust valve is fully opened or closed then you should look into adding an OBD plug-in that features Bluetooth valve control from your phone. During testing, the best way to choose whether your valve is open or closed for your sound preference is through an OBD-linked application on your phone. Included in this kit are optional OBD extensions to not only gain diagnostic function but also gain the ability to influence widgets on your vehicle such as valve position on your valved muffler.

The wait is finally over, if you have been driving your E46 M3 around with a stock exhaust or are looking for your final exhaust setup we have you covered! Welcome to the world of ingenious designed exhausts that can meet your every driving need. Our new E46 M3 catback Exhaust is a stunning example of both engineering and art with sounds to please your ears and a sight to remember. Our catback is a lightweight and free-flowing exhaust that features two independent valved mufflers and an ingenious mounting system that is a pleasure to install and easy to perfectly dial in the exhaust fitment. Weighing 19lbs or less than your factory exhaust, featuring mufflers specifically designed for the S54 this exhaust is able to provide two completely different driving experiences.
With the exhaust valves closed the refined driving experience will blow your mind; while daily driving with closed valves there is a perfect bump in volume over the factory exhaust which allows you to hear and feel your rpms with a smooth exhaust note that shows your true passion for your iconic vehicle. Now on to the real action, what you have always wanted but never wanted to commit to. Some days you just want to put the pedal to the floor with unlimited amounts of exhaust volume with your high revving 6 cylinder. Here is your opportunity to unleash the pure sound of your S54 while having the choice to change back to a respectable volume exhaust. With the valves open this exhaust is an absolute mental, untamable racecar. Starting off from a stop with the valves open there is a significant increase in volume over the valves closed. When entering in to the 2000 rpm range you begin to experience the slightest taste of how satisfying the exhaust is going to sound. As you approach 4,000 rpms and higher you now have started to open up the can of worms, you can feel the free flowing path of the exhaust with limited to no resistance, far superior to the factory exhaust. Anything after 6500 rpms is an absolute statement of exhaust. Over 6500 rpm is a sonorous note that lives rent free in the enthusiasts mind that can make a believer out of anyone who doubted the capable E46 M3. Once you are done having your fun and have experienced your S54 more than you ever have all you do is make one button click on your valve controller and you are back to high class and refinement. Truly the best of both worlds and a school girl giggling experience anytime you want.

Performance Catback Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the N55 for an iconic driving experience.
Take your N55 to the next level and show the S55 drivers who is boss with our Turner Race-Inspired Catback. This light weight and free flowing exhaust boasts a smooth, clean, and rowdy exhaust note. Although the N55 found in the F chassis of BMW features a loud "cold start" once the car is warmed up the exhaust lacks character and volume. The twin scroll turbo featured on your M2 does a great job of limiting the volume on the factory exhaust but we want to hear the exhaust! No more boring and subtle exhaust, in comes our Turner catback to drop weight, get rid of restrictions and release the full engine and turbo sounds!
When you are shopping for an F87 M2 you have two options to choose from. Your choice can be the standard M2 with the N55 engine or the M2 Competition that comes equipped with the S55. The best part about either the competition or non-comp M2 is you are still getting the "M" suspension, characteristics and drive. From our experience there is not a big trade off between the two models that can justify the price difference. With the N55 you get a lighter weight and extremely capable weapon. Paired with an intake, tune, and the our lightweight exhaust the M2 is not a car to be messed with.
We set out to amplify the N55 M2 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced your exhaust weight to a total of 28lbs, and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin scroll turbo inline-6 N55 engine. The increase in flow is gained from true 3.0" 304 stainless steel front section that feeds into the straight-through free flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory mufflers and resonators with straight through lightweight stainless for the most weight advantage possible. The best part of the race inspired catback is the capability to perform far beyond the point that the factory exhaust.

Experience a more engaging driving experience accompanied by weight savings, increased flow, and most importantly an exhilarating exhaust note!
The G87 is no stranger to performance. Right out of the box the new M2 features rocket-like acceleration, and great handling and is even offered with a manual gearbox. With the Turner Performance exhaust, you get a more engaged feeling improving the driving experience. Increased sound you can both hear and feel offers a direct line of feedback between you and the car. The added volume allows you to feel where you are in the power band without looking at your rpm gauge allowing you to feather the exhaust around turns and when shifting in your manual transmission. Along with the increased volume and feeling our exhaust features smooth transitions and improved flow for improved throttle response and sound on deceleration.
Our mission was to amplify the G87 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 18 lbs, and delivered an exhaust system that captures the full unrestricted sound of the twin-turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into a free-flowing valved muffler. Our team designed this catback with flow in mind to ensure the exhaust would never be restricted. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a modest weight advantage free from the added weight of the bulky factory muffler. Paired with our exhaust is a valved muffler that allows for both a smooth tone and rowdy exhaust note that can be controlled with factory options. All of this plus the direct fitment and straightforward installation leads to our Turner Performance Catback exhaust being the clear answer in your mission to find the best exhaust for your S58-powered M2.

Here at Turner our mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from smooth flow path dual 3.0" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our muffler flows better and sounds better than the stock muffler.

All of this plus the direct fitment and straight forward installation leads to our valved exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.
The G80 took the world by storm by breaking the mold of BMW's standard design language. With the G80 and G82, a whole new generation of M car owners emerged. At first people were hesitant about the larger more distinguished front grilles, but after the shock was gone the true glory of BMW's newest M cars began to shine. The G80 M3 and G82 M4 are incredibly capable cars out of the box and Turner's large range of upgrades means the sky is the limit. Give your G80 or G82 the aggressive exhaust note that you wanted from the factory with Turner Motorsport's G80 G82 Stainless Valved Catback Exhaust.

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

This Supersprint performance exhaust is built from the Euro M5/M6 exhaust layout but fits the E24/E28 (see fitment notes below). It features oversized dual 50mm stainless steel pipes leading from the catalytic converter. This Supersprint system has a center resonator and rear muffler with free-flow designs for a sporty sound and less restriction to free up horsepower. Both systems are bolt-on to the stock factory catalytic converter (see fitment notes below) and use all of the stock hangers and gaskets. This makes for an excellent replacement exhaust system because the sound is such a great match to the M30 engine and retro cool that these cars have now. It's a classic growl and throaty sound without being overly aggressive. We've had nothing but compliments on the sound from this system. The previous mild steel versions have been discontinued - this system is now 100% T304 stainless steel!
Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Fitment Notes: This system is not a direct fit with the US catalytic converter section. The factory system is connected with 2-bolt flanges but the Supersprint Euro system is based on the Euro 3-bolt flanges. The US cat section flanges must be removed and replaced with the triangular 3-bolt flange (BMW p/n 18111178137) and gaskets (p/n 18301723886). Or, conversely, remove the 3-bolt flanges from the Supersprint and re-weld the old 2-bolt flanges from the stock resonator section.

When we set out to build an exhaust for the BMW E46 323/328, we knew it needed to match how you drive and how you want your car to sound. We also know that while many drivers wish for an aggressive, head-turning exhaust note, they don’t always want the volume all the time. That’s why we engineered this lightweight Turner Motorsport performance exhaust system with a fully valved muffler, giving you the ability to switch between a refined, quiet tone and a loud, spirited sound at any moment.
Our new Turner Cat-Back Exhaust is the first valved rear section designed specifically for the E46 323/328. With the included remote controller, you can change your exhaust tone with a simple click. With the valve closed, the system delivers a smooth, deep, tasteful note for daily driving. Open the valve, and you unlock an aggressive, free-flowing exhaust tone that brings out the full character of the M52 engine, perfect for track days or anytime you want maximum sound and performance.
For maximum flow and durability, we built this system using dual 2.0" T304 stainless steel mid-pipes that bolt directly to your factory downpipes. Inside the mid-section, we integrated an X-pipe to balance exhaust pulses, reduce backpressure, increase performance, and smooth the exhaust note. The dual 2.0" mid-pipes merge into a 3.0" axle-back section and a full 3.0" valved muffler, finished with bold 3.0" integrated tips that perfectly fill the E46 rear bumper.
Modern performance cars use valved exhaust systems as standard equipment, but the E46 never truly benefited from that technology. Some early E46 models used a basic vacuum-controlled valve, but after nearly 20 years, most are no longer functional. By studying BMW’s original concept and improving it with modern engineering, we created a lightweight, high-performance valved exhaust that gives your BMW E46 323/328 modern sound control, better flow, and a dramatically enhanced driving experience.

We set out to amplify the F80/F82 with a proper exhaust system. To accomplish this goal, our engineers at Turner increased flow and delivered an exhaust system that captures the full unrestricted sound of the twin turbo inline-6 S55 engine. The increase in flow was gained from dual 2.5" stainless exhaust pipes that feed into one of the best designed mufflers on the market. Our in-house engineers specifically designed the muffler with flow in mind to ensure that even with the exhaust valves closed, our Turner muffler flows better and sounds better than the stock muffler. The best part of the catback exhaust is the capability to control just how aggressive you want to your exhaust to sound, far beyond the point that the factory exhaust is able to perform. All of this plus the direct fitment and straight forward installation leads to the Turner Stainless exhaust being the clear answer in your mission to find the best exhaust for your S55 powered F80 or F82.
Transform the whole dynamic of your M3 or M4 with added performance, increased flow and not to mention the absolutely wicked sound you get from the upgraded Turner Performance Catback!

Performance Catback Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the S58 for an iconic driving experience.
If you have driven an S58 car, even in stock form it feels like the sky is the limit.(If you haven't driven one, we are not sure why you are even looking into this exhaust)
When your driving an S58 equipped car such as the G80 M3 you can put your foot to the floor and it feels like the car would keep going and going, possibly with no limit. The G80 driving experience is great but there is always room for improvement. if dropping over 40lbs from just your exhaust and the gain in flow alone aren't enough to sell you, no problem. From enhancing the exhaust with smoother flow paths and taking out the bulky and restrictive muffler we saw gains up to 10hp and 14lb of torque on the stock ecu with zero tuning. Now that there are options for plug and play tunes as well as unlocking your ECU for custom tuning there is a much larger upside for power improvements. You will have to find the other restrictions holding you back from more power because it wont be the exhausts fault, this is as free flowing as it gets.
Here at Turner our mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 26lbs, and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into straight-through free flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a more-than-modest weight advantage. The best part of the Race Inspired catback is the capability to perform far beyond the point that the factory exhaust. All of this plus the direct fitment and straight forward installation leads to our Turner Race Inspired Catback exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.
