BMW E93 Performance Exhaust Systems

BMW E93 Performance Exhaust Systems BMW Performance exhaust systems are tuned by in-house BMW engineers to subtly enhance the sound and performance of your BMW. They have engineered these systems to fit perfectly, sound beautiful, utilize advanced materials, and blend with the styling of your car. BMW Performance exhausts are not too loud - focusing on enhancing the sound rather than blaring it. By opening up the exhaust and removing restrictions, the engine can work less to move the exhaust gasses through the system. This means a bit more power in addition to that sexy growl they produce.

Genuine BMW Performance Inconel Exhaust - E92 M3, E93 M3 - 2008+ As used on the Lime Rock M3 Project Car
With the racetrack and the street in mind, this new exhaust system is crafted from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel®. This flow optimized exhaust system reduces exhaust backpressure and allows the M3’s 414 horsepower S65 V8 engine to produce an even more powerful sound. Inconel’s unique qualities allowed engineers to reduce the thickness of the tubing from 1.5mm to 0.8mm. This resulted in a weight reduction of approximately 40%, or about 20 lbs. when compared to the stock exhaust system. Inconel has also proven to be very corrosion resistant and has been used at the highest level of Motorsports. The M Performance Exhaust includes perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. It represents the ultimate in technology and sportiness, accentuating the individual character of the BMW M3. The exhaust was developed using state-of-the art CAD and FEM technology ensuring optimum fit and OEM quality.

GruppeM 70mm Titanium Exhaust System  --  BMW E92 E93 M3

GruppeM designs some of the highest quality intakes and exhaust on the market. Using advanced techniques to get optimized efficiency using specific pipe diameters, they are able to produce an exhaust that not only performs amazingly, but sounds amazing too. Gruppe M's exhaust systems are designed to fit the same as the stock exhaust, eliminating guess-work, allowing for quick and clean fitting systems that require no custom fabrication or assembly. An important detail is their Titanium construction, reducing weight significantly and giving a dry, high-pitch exhaust note that you can't get with standard stainless steel. An added benefit of titanium contruction is that over time heat from the exhaust will change the color of the exhaust system.

Exhaust Features:

  • Optimized exhaust pipe sizing
  • Ultra-lightweight titanium construction 
  • Racy, high-pitched exhaust note at high revs and heat color gradation
  • Dual 80mm exhaust tips
  • Shot processed stainless steel tail end (made of stainless steel)

For car enthusiasts, one of the key aspects to your car is the sound. That being said, in can be very difficult to find the right exhaust that gives you the right note. Sometimes too loud, other times too quiet and just not always what you want. Now, you no longer have to choose between loud or quiet thanks to Innotech Performance (iPE). They have created and exhaust system that gives you the perfect blend of performance and sound while giving you control at your fingertips. 

Innotech takes pride in becoming an industry leader in the high performance exhaust community. They've reached this feet by specializing in valvetronic exhaust systems. What is valvetronic? Valvetronic is the term for valve-controlled exhaust technology that delivers power and control to the driver’s seat. Operated by a remote control, these systems have 3 different settings: on, off, auto. With the system set to on, the valves are fully open for the best performance and sound. When set to off, the valves close, resulting in significantly reduced sound. The final setting is off, which may be the best option for most. The system detects RPM and fuel pedal signal and adjusts the valve accordingly for the ultimate driving experience. 

Each part of the exhaust system is individually designed to fit it's application perfectly. The unique designs overcome the limits set by the stock exhaust, so that performance, sound, and driving pleasure can be increased dramatically.

Kit Includes

  • Valvetronic Muffler
  • Quad polished tips
  • Remote control kit

Genuine BMW Performance Exhaust System for E92/E93 328i, 328Xi This is a factory BMW Performance exhaust for the 2007-2013 E92/E93 328i, 328Xi Coupe & Convertibles. This is a factory BMW accessory so it fits great, looks and sounds phenomenal, and is exceptional quality. The sound is mildly more aggressive than the stock exhaust with a slightly more throaty note. This exhaust will waken up the stock 328 personality with a better sound and improved flow. If you feel the stock exhaust is just TOO quiet this is a great option without going overboard. To quote one user, "It feels much different than a stock 328i. Quiet enough to sound classy, and a clean sporty growl when you rev it up."

This exhaust is a two-piece system that includes the rear muffler and center resonator. On some models you will need to cut the stock exhaust after the resonator to install this; other models are already a two-piece system. A BMW factory exhaust clamp is included to mount to the factory cat section. We also recommend using the exhaust sealing paste to ensure a leak-free install.

This item fits the following BMWs:
