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.

Includes: Downpipe with High Flow Metallic Cat, 3" Gasket, Hardware
Fits: 02-07 WRX, 04-07 STI, 04-07 Forester XT
