Cobb Tuning Turbo-Back Exhaust 2002-2007 WRX/STI

The Cobb Tuning turbo-back exhaust for 2002-2007 WRX and STI is a complete, truly engineered system that offers optimal performance, tasteful looks, and unparalleled durability without a loud and obnoxious exhaust note. A cast stainless steel bellmouth empties into mandrel bent 3" piping, a state-of-the-art Cobb-exclusive GESi metallic substrate catalytic 300-cell high-flow converter, and back to a low restriction straight-through muffler that tucks up nicely under the car, ending in a tasteful but not overstated 3.5" double wall tip featuring an etched COBB logo. This exhaust system conforms to the SAE-dictated 95-decibel exhaust noise level limit enforced by California, as well as other states in the US. The kit includes a gasket for the rear section and cat-back, but does not include the turbo-to-downpipe gasket.

Note that this downpipe will require custom ECU tuning.

Fits all 2002-2007 Subaru WRX and WRX STI.
