Free ground shipping! This Euro center resonator replaces a stock European-spec center resonator or US/Euro catalytic converter section. The Supersprint exhaust piping is 60mm in diameter - 10mm larger in each pipe than a standard US exhaust system. This larger sizing helps to improve exhaust flow which frees up horsepower from the engine. Instead of working to push exhaust gas through small pipes the exhaust gas flows easier so the engine doesn't have to work as hard. Now constructed with 409 stainless steel piping! The Supersprint Euro center resonator replaces a stock BMW Euro M3 center resonator OR requires the full Supersprint Euro headers and Euro rear muffler. For the best flow with supercharging or intricate intake kits, the Euro system works best! section: center resonator connects to: stock Euro headers, stock Euro muffler material: T409 stainless steel

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!

 

This part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.
