This Supersprint center section replaces the stock facatory catalytic converter and includes a tuned center resonator. This Supersprint resonator was designed to replace the stock center section on Euro non-cat 1987 E30 M3s. This is a direct replacement for the stock cat and perfect if your cat is no longer needed or has failed. And with a free-flow design you can expect a 5-7hp gain over the stock cat section.

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!

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

Why Supersprint?

Supersprint performance exhaust for the M42 E30 318is gives a nice throaty and ripping sound. The Supersprint muffler is much freer-flowing than the stock exhaust which frees up horsepower in addition to improving the sound. This is a true cat-back system that bolts on to the stock catalytic converter and uses all of the same factory gaskets and hangers.
