Part #: PSP-EXT-055
The Perrin Performance Equal Length Subaru WRX and STi Header has quickly become one of the most popular Subaru aftermarket header choices due to proven power gains of up to 30 wheel horsepower and 30lbs of torque on a slightly modified STi! The Perrin manifold is a true equal-length WRX & STi header constructed of 304SS.
The Perrin Performance WRX & STi header is designed to make large power gains without sacrificing low-end power. Flanged for a stock uppipe, the Perrin header is compatible with stock-location uppipes, including those included with rotated-mount turbo kits, making the Perrin manifold an excellent choice for big-turbo Subarus.
The Perrin Performance equal-length header is designed for the 2.5 liter 04-20 STi, 2006-14 WRX, and 05-08 Legacy GT, but it will fit the 02-05 WRX with the purchase of a 2.5L oil pan. If you are looking for huge power gains, this is the header for you.
This does NOT fit the FA20 Subaru WRX.
02-05 wrx requires 2.5l sti oil pan (on some)
06-07 wrx requires sti oil cooler and sti oil pan
