Perrin Uppipe Subaru WRX STI 02+

PERRIN has been known since our inception for the quality of our up-pipe. After all it was the first part we ever released and has been a leader in this market ever since. We have always used the finest materials and maintained proper size, shape and tolerances to make every installation a breeze. Made from 321 stainless steel and 1/2flanges this is guaranteed not to warp, leak or fail. Power increases are consistent and strong. Our up-pipe is still one of the best and first ways to increase the power and throttle response on your Subaru.
