The Race Pipes, combined with STILLEN's new performance headers, produce big increases in power and torque. Contributing to the performance gains along with the straight-through free-flowing design, is an expansion chamber that promotes more efficient exhaust scavenging.

For example, the combination of STILLEN Headers and Race Pipes yield performance gains of 16 hp at @ 6200 RPM and 20 lb/ft @ 3800 RPM at the wheels for a 2003 Nissan 350Z as tested on the STILLEN Dyno.
With STILLEN's 18 years of experience in designing and manufacturing Nissan performance parts, you should have complete confidence that every STILLEN product is of the highest quality and has under gone extensive research and development before production.
