E-mail this product to a friend

Perrin has been known since their inception for the quality of their uppipe. After all it was the first part they ever released and has been a leader in the market ever since. Perrin has 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 uppipe 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 benifit to installing a Perrin uppipe on your 02-05 WRX is that is protects turbo from damage if the OEM EGT probe breaks off. On these years, Subaru installed an EGT probe into the stock uppipe. On heavily modded cars this can break off and destroy the turbo! Perrin's uppipe removes this sensor all together.  The sensor is perfectly ok to remove as it is not controlling of any other aspect of the car. Included with each uppipe is instructions how to defeat this turbo killing feature of the OEM pipe!

Fits:
 - WRX 2002-2009*
 - STi 2004-2009
 - Legacy GT 2005-2009*
 - Forester XT 2004-2009*

*NOTE: These models contain OEM catalytic converters in their uppipe, and it is NOT legal for use or installation within the United States on those applications. However, Canadian, Japanese, European and other markets may allow for replacement. Contact your local government prior to ordering for these areas. For those installing this part on race cars, there is an EGT sensor that is installed into OEM uppipe.  This part has been proven to fail and destroy turbos in racing applications. Perrin purposefully eliminates the EGT bung to prevent turbo failure. A CEL will occur after installation of the uppipe in this situation, unless a 2.2Kohm resistor is installed across the OEM female plug. These can be found at most any RadioShack.
