SPM Stainless Valved Exhaust System Audi R8 4.2L V8 06+

The Steve Petty Motorsports Audi R8 exhaust systems are the most refined, meticulously built, and brutal exhaust systems available. Each system incorporates uniquely valved passages that work in unison with the OEM specifications to control the sound and volume of your engine.

Under partial throttle the valves keep the system's airflow controlled and tame, but under wide open throttle it opens up and unleashes the true muscle of the 4.2L R8. The SPM fully vacuum-actuated valved R8 exhaust systems have set the new standard in R8 performance and quality. The entire SPM system is refinement and power all packaged into one system, satisfaction and workmanship are always guaranteed.
