Perrin Downpipe Front Section Subaru WRX 02-05 & STI 04-07

Crafted from 304 Stainless Steel, PERRIN down pipes use mandrel bent 3" tubing, insuring a streamlined exhaust flow and making crisp boost and throttle response when needed. This PERRIN downpipe uses a 200cell per inch metallic substrate catalytic converter. Unlike the OEM ceramic brick style catalytic converter, these converters have high flow rates and are guaranteed to take the extreme heat produced by high horsepower Subarus.

The signature split pipe mouth diverts the wastegate exhaust gases away from the exhaust coming from the turbine. PERRIN downpipes use thick laser cut stainless steel gaskets. Our thick flanges will not warp or leak during extreme driving and mate perfectly with stock or aftermarket components. Perrin down pipes are TIG welded and polished to a mirror finish for a professional, clean, show quality look.

NOTE: 2002-2005 Subaru WRX & STI down pipe is approved for all states that do not require CARB approval.
