Perrin-Downpipe/Uppipe-WRX/STI
Perrin's WRX & STi high-flow cat downpipe sections utlizes 49 state legal catalysts to keep you emissions friendly and improving power at the same time. Perrin utilizes high efficiency metal substrate catalysts for optimal performance. These are legal in 49 states as replacements for a defective, missing, or worn catalyst but are NOT CARB legal.
Perrin WRX, STi, and Forester XT sectional downpipes feature 3" polished stainless steel piping, with a diverted wastegate design for optimal flow. Perrin's wastegate diverter separates exhaust gases behind the turbo and channels them into the exhaust path further downstream to reduce turbulence and improve performance; resulting in smooth, optimized performance. The Perrin WRX & STi downpipes use a 1/2" thick flat flanges to prevent warping, and will bolt to an aftermarket or stock catback exhaust. Perrin's Subaru downpipe catalysts are backed by a limited warranty.
