PERRIN Front & Rear Down Pipe Sections
Approved for all states that do not require CARB approval.

Construction
Crafted from 304 Stainless Steel, PERRIN down pipes use mandrel bent 3" tubing, insuring a streamlined exhaust flow. Making crisp boost and throttle response when needed.

High Flow cat
This PERRIN downpipe uses a 200cell per inch metallic substrate catalytic converter. Unlike the OEM ceramic brick style catalytic converter, PERRIN converters have high flow rates and are guaranteed to take the extreme heat produced by high horsepower Subarus.

Exhaust Diverter
This downpipe has a signature split pipe mouth to divert the wastegate exhaust gases away from the exhaust coming from the turbine.

Thick Flanges
PERRIN downpipes use thick laser cut stainless steel gaskets. Their thick flanges will not warp or leak during extreme driving and mate perfectly with stock or aftermarket components.

Welding & Finish
Perrin down pipes are TIG welded and polished to a mirror finish for a professional, clean, show quality look.

Fits:
 - 02-07 WRX
 - 04-07 STI
 - 04-07 Forester XT
