Perrin Equal Length Headers Subaru WRX STI 02+

Reaching back to lessons learned by tuners in our past, PERRINhas grabbed a dramatic power increase that was previously bottled up by the factory manifolds. Whether normally aspirated or turbocharged, proper exhaust gas scavenging is vastly important. The turbocharger relies on energy from the exhaust flow to rotate its blades. By pulling additional energy that was otherwise wasted by the factory manifold we can transfer that to the turbo to decrease spool up times and improve power. Our R&D staff was able to manipulate the length and shape of each runner to allow easy installation and still maintain large power increases.

Constructed from 321 stainless steel and 1/2 flanges the header is designed to withstand the most punishing levels of heat your engine can dish out. Fit 2002-2008 models.

Fits all Subaru Turbo Models
WRX models will require a STi type oilpan for clearance.
