Perrin Down Pipe Single Piece

3" Stainless Downpipe with a Highflow Cat

We brought back an old classic! Back by popular demand is the PERRIN Single piece 3" downpipe with single high flow cat!!

Crafted from 3” 304 Stainless Steel, mandrel bent and TIG welded, this product insures smooth exhaust flow back to the catalyst. Making crisp boost and throttle response when needed. Just like all other downpipes we have made for the WRX, we have signature split pipe mouth to divert the wastegate exhaust gases away from the exhaust coming from the turbine. This small feature is what makes our part really stand out from the rest!

Our downpipe uses a 200cell per inch metallic substrate catalytic converter. Our converters are guaranteed to take the extreme heat produced by high horsepower motors and do so for miles and miles. (See warranty details included with each.) Contact PERRIN or your local dealer for additional information.

The PERRIN Performance downpipe is the perfect compliment to your PERRIN 3" exhaust system. Like our other exhausts, the 02-07 WRX/STI downpipe w/cat is built with 3” 304 Stainless Steel tubing, which passes through a special high flow metallic catalytic converter. All mirror polished for that show look.
