If you have already upgraded to the Turner midpipes this is your chance to step up to the full valved catback. See the details when creating your new Full Catback! With this Valved muffler and all installation hardware you can add to your Turner midpipes to make a full exhaust. 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 Turner motorsports you no longer need to choose between rowdy and tame. With the new your new light-weight performance exhaust you have the option to go from tame and tasteful to loud and rowdy. The Turner 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 you're at the track or just in the mood to let it rip. The full catback exhaust from Turner features dual 2" 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" 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, the engineers at Turner revitalized this cool technology and made it better. The final product is a light-weight performance exhaust that features superior valving a great aesthetics!

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.

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.

Borla completely re-engineers the exhaust on the E46 325/330 with a tuned all-stainless cat-back system. The E46 Borla bolts straight to the factory manifold and uses all of the factory hangers for an easy and seamless install. Your factory exhaust can come off as one complete piece and bolt this in its place! This is a full stainless system - T304 inside and out for maximum corrosion resistance. The Borla flows better than the stock system too for increased performance, even over the stock ZHP system. But we love the sound of this system the most - deep and with plenty of rumble to set it apart from the stock sound. It's a tuned system, with front resonator and rear muffler, to be louder than stock but not excessive. It's also a lot lighter than the stock system at only 33lbs from nose to tailpipe.
Read what Borla owners have to say: "The difference over stock is noticeable the instant you turn the key. It begins with a deep muted rumble at engine start. Between 1200-2000rpm, you are treated to a nice throaty (and somewhat loud) growl. Between 2500-3500rpm, the deep growl reveals a slightly deeper, more melodic mechanical rev-up. Once past 4500rpm, the car begins to sound surprisingly stock, all the way up to redline. Lifting off the gas reveals a slightly more pronounced "burble" that settles into a low rumble as revs drop back to idle. At steady cruising speeds, the exhaust does not drone. Planting your right foot brings back that wonderful low growl." "...the Borla is a very well built unit. Very civilized exhaust note... more agressive, yet not obnoxiously loud." "I can easily say the Borla exhaust is much better than the X&X exhaust. My brother has the Borla on his 330i ZHP, and I had the X&X on my 330i. The X&X exhaust didn't have the quality of engineering compared to the Borla. The X&X was louder, and had horrible resonation - unacceptable for street use. The Borla is bolt-on, excellent quality, and hangs perfectly straight. The sound is a bit louder than stock, yet never "rice" or obnoxious."
Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on all of every Turner BMW racecar.

Drop 10 lbs and replace your midpipes/resonator for a free flowing X-Pipe to get a smoother sound and decreased back pressure!
An X-Pipe can do wonders for your engine for performance and sound. Exhaust gasses come out of your motor in pulses from each individual cylinder, with a cross-over or x-pipe the exhaust gasses meet in the middle and combine. The result of the combining gasses is a smoother path leading to lower amounts of back pressure, a more free-flowing exhaust and leads to increase power and response. Combine with a new rear muffler for best results!
BMW's straight six motors have been referred to as sounding like chain-saws, and being "raspy" or "metallic".

BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.

Upgrade your BMW E46 exhaust system with the Turner Motorsport X-Pipe, ditch the bulky factory midpipes and resonator, reduce backpressure, and let your engine breathe the way it should. This free-flowing X-pipe delivers smoother exhaust tone, improved throttle response, and a noticeable performance advantage over restrictive OEM components. Factory exhaust pulses exit each cylinder separately, creating turbulence, rasp, and unwanted backpressure. A performance X-pipe merges and balances these pulses, producing a cleaner, deeper exhaust note while increasing overall exhaust efficiency. For the best sound and power gains, pair the Turner X-Pipe with a high-flow performance rear muffler. BMW’s straight-six engines, especially in the E46 323i and 328i, are known for their metallic “rasp” under load. Turner’s mid-section with an integrated X-pipe dramatically smooths the exhaust character, enhancing tone without sacrificing flow. Each system includes upgraded hardware for the downpipe connections and premium stainless steel exhaust sleeves for a perfect, leak-free fit to your factory rear section.

Rogue Engineering is proud to introduce their DMS (Dual Muffler System) exhaust systems for the E46 (non-M) in its latest offering to the performance exhaust marketplace.
What makes the DMS unique? Like all Rogue Engineering products, the DMS exhaust system is entirely designed and developed in the US in our facility in Hohokus, NJ. By doing the development, fitting, evaluation, and testing here, you're assured a product that not only looks and sounds great but a product you can have installed with confidence.
How much performance should I expect to gain? In testing, replacing only a muffler or even the complete exhaust system on an E46 yields small measurable gains. Of course, these minute gains may be depicted on a carefully constructed dyno chart. Rogue Engineering looks at an exhaust with reality in mind, designing our exhaust to deliver great looks and sound, with minimal issues of fit. Of course, all of this at an affordable price would be a bonus. These are features that the Rogue Engineering DMS deliver!
For real-world exhaust performance gains, this typically means replacing the largest restriction, the catalytic converters, located in the factory exhaust manifolds. From there, free flow aftermarket catalytic converters could be added downstream, after the exhaust gas velocity had an opportunity to accelerate out of the engine, allowing for the most LEGAL gas velocity allowable. This course of action, however, typically can exceed more than $3000 plus installation.
Replacing the ENTIRE factory exhaust system (resonators and rear muffler) with larger tubing WITHOUT addressing the largest restriction is an exercise in futility. This kind of exhaust "upgrade" will generally cost needless additional installation charges, fit issues (can 6 clamps on an exhaust REALLY fit like factory?), and ultimately, drain your wallet faster than a Bugatti Veyron.
DMS Features Just because the DMS exhaust system is easy on the wallet does not mean you are getting short-changed. Features of the RE IKON E46 system include:
Full T-304 Stainless Steel construction
Mandrel bent, dual 57mm tubing (stock is dual 50mm) eliminates center resonator, allowing for increased air flow yielding positive performance gains.
Mill-finished pipes and muffler, mirror polished dual 3" staggered RACE tips fits most aftermarket bumpers (Hamann, MTech, AC Schnitzer)
Entire exhaust utilizes TIG welded construction
Maintains BMW factory warranty
Rogue Engineering logo tastefully welded onto the top of the muffler
Can be clamped or welded (because factory exhaust must be cut, professional installation recommended)

The Supersprint rear resonator for the E46 M3 is designed to help you tune your exhaust to your personal taste. If you're not a fan of the stock raspy exhaust note of the M3 this Supersprint resonator can help to reduce it. Or if extensive exhaust modifications have made the exhaust too loud this resonator can help quiet and dampen the overall volume. This fits in section 2 of the exhaust - after the front resonator section 1 and before the rear muffler.

These Supersprint metallic sport cats are for the E46 M3 with Supersprint's own stepped headers. The piping is slightly oversized and the Supersprint sport cats are much freer-flowing than a traditional stock cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will only mount to the Supersprint full stepped headers (p/n 044001) and then to any section 2. These cats are built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed).

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

Want more rasp and volume to come through from your exhaust? This Supersprint section 2 will replace and delete the factory resonator that sits before the muffler. Without the resonator there to dampen the sound the overall volume will increase and let more S54 rasp come through. Combine this with the Supersprint section 1 straight pipes for even more Motorsport rasp. This section 2 pipe will bolt up to a stock section 1 or cat section and any muffler. It's perfect for getting just a little more volume from your stock exhaust without changing the muffler. We blogged about it! Check out E46M3blog.com for more detail.

When building your vehicle for the track, there are a lot of considerations to take into account. One major factor is your exhaust system. Many exhaust systems are only designed for so much exhaust flow, which can really limit the total amount of potential power your engine can produce. To address this issue with heavily tuned, turbocharged, or supercharged E46 M3s, Supersprint now offers a new line of high performance Center Twin-Pipe Exhaust Pipes that are designed to provide you with a significantly higher exhaust flow than their original performance exhaust pipes, 787503 (Resonated) and 787513 (Non-Resonated), designed for street and light track performance.
This twin pipe system utilizes two high flow pipes instead of a single large pipe, allowing for up to 25% greater total exhaust flow. Thanks to the increased total flow, these center pipes are capable of supporting S54 engines producing over 400whp, perfect for all highly modified street cars or performance track vehicles.
This specific option offer's pipes that are resonated to prevent excessive noise and drone that may be experienced at cruising RPM speeds.
This direct fit Bosch oxygen sensor plugs directly into your factory connector. Fits M44 engine Z3 and 3 series and M62 engine E39, E38, E31 with V8 engines. No cutting or splicing required. A new oxygen sensor can improve driveability and lengthen engine life. Bosch part number 13559.

Rasp Terminator for the E46 M3 (also for MZ3 and Z4M) is a tuned front section that: Greatly reduce rasp from the S54 engine Balance exhaust pressure for each bank with H-pipe crossover The S54 rasp is excessive and tuning it out requires the right combination of resonators, placement, and tubing size. CPI designed their own section 1 after other designs on the market fell short. Rasp is reduced by approximately 80% on a M3 equipped with aftermarket headers. The latest RTX incorporates an H-pipe crossover that equalizes exhaust pressures in both banks before they merge for section 2. This reduces turbulence and improves exhaust flow. While not designed to gain power and torque, dyno testing showed slight gains with this system. Fitment has also been improved for better ground clearance. Tubing is a full 2.36" (60mm) and 304 stainless steel throughout. It will bolt on to most headers and to any section 2 that uses the factory-style flanges.
