The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound. Its genuine straight-through design ensures the utmost high RPM power, while the 2.5" or 3" perforated core effectively eliminates backpressure, optimizing exhaust flow.

This muffler stands as the ideal choice for dedicated racers, turbocharged engines, nitrous oxide fuel systems, or vehicles equipped with wild cam applications. It boasts a 2.25" inlet, a 24" overall length, and a 4" diameter round, angle-cut tip.

Kindly note that this muffler is of universal fit for rear exhaust and may necessitate welding or fabrication for installation, as it is not a direct bolt-on component for any specific vehicle.

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!

NOTE: Supersprint engineers and manufactures complete exhaust systems. This part was designed to be used with the rest of the Supersprint system on this car but may be used on its own. Contact us for more details.

Supersprint's classic sound for the E30 M3 produces a ripping, Motorsport-inspired wail, especially when combined with the center resonator section. This rear muffler is a slip on cat-back system in a new stainless steel design (the old material was a coated mild steel). Rear muffler alone will give you an excellent hair-raising exhaust note that won't be mistaken for anything but an S14.
