The Perrin Performance equal length header for the Subaru WRX, STI and Legacy GT 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 full T304 stainless steel. 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 WRX & STI, 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 product will only fit 02-05 WRX models with the purchase of an 2.5L oil pan, sold separately.
Perrin 04-08 STi /LGT/FXT/06-08 WRX (06+ WRX requires modification to oil cooler)
Wrapping this header with exhaust wrap will void Perrin's warranty on this product.
