PERRIN has been known since Perrin's inception for the quality of their up-pipe. After all, it was the first part they ever released and has been a leader in this market ever since. They 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 1/2 flanges, this is guaranteed not to warp, leak or fail. Power increases are consistent and strong. Perrin's up-pipe is still one of the best and first ways to increase the power and throttle response on your Subaru.
Why go with a cheap imported imitation when you can have the original? Perrin's uppipe matches the OEM exhaust manifold outlet and OEM turbo inlet. This creates a smoother free flowing exhaust path to the turbo. In turn, this reduces spool up time.
A benefit to installing a PERRIN uppipe on an 02-05 WRX is that is protects turbo from damage when the OEM EGT probe breaks off. On these years of cars, Subaru installed an EGT probe into the stock uppipe. On heavily modded cars this can break off and destroy the turbo! Perrin's Up-Pipe removes this sensor all together. The sensor is perfectly ok to remove as it is not controlling any other aspect of the car. Included with each uppipe is instructions on how to defeat this turbo killing feature of the OEM pipe!
