BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 3 Series E46 (1999-2005)

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!

Sound + Power + Quality = the ultimate exhaust upgrade for the E46 M3. The Supersprint Race exhaust has a lot of fans, us included, with the mufflers producing an intoxicating shriek. This system covers the entire E46 M3 exhaust - headers, section 1, section 2, and rear mufflers with special discounted pricing. Although sound is subjective we feel the full Supersprint system produces the sexiest, most thrilling exhaust sound. It's an exotic, European-type sound unlike most American-made rumbling exhausts and it blends perfectly with the technical sophistication present throughout the E46 M3. This system does not diminsh the rasp inherent to the S54 but it's a refined and tuned sound that has won over many fans. And it's not all about the sound. Full system details:

• Stepped Headers - replaces factory manifolds and cats; equal length stainless tube in increasing stepped sizing
• Section 1 - matching stepped sizing straight pipes or metallic catalytic converters
• Section 2 - with or without resonator cross-over pipe

• 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!
