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, thisproduct insures smooth exhaust flow back to the catalyst. Making crispboost 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 theextreme heat produced by high horsepower motors and do so for miles andmiles. (See warranty details included with each.)  Contact PERRIN oryour local dealer for additional information.  

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