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 preference. 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!

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.

Turner Motorsport Conforti Performance Chip and Supersprint exhaust - a match made in heaven! 

Why Supersprint?

Supersprint's classic sound for the E30 M3 produces a ripping, Motorsport-inspired wail. This rear muffler is a slip on cat-back system in a new stainless steel design (the old material was a coated mild steel) - the tear muffler alone will give you an excellent hair-raising exhaust note that won't be mistaken for anything but an S14 but we recommend the center section as well for ideal tone and volume.
