COBB Tuning Stainless Steel Turboback Exhaust - WRX 2002-2007 - STI 2004-2007

The COBB Tuning Stainless Steel 3” Turbo Back Exhaust was designed to be everything customers are looking for in an exhaust system -- a complete, truly engineered system, that offers optimal performance, tasteful looks, and unparalleled durability without a loud and obnoxious exhaust note.

The system is offered with a high flow catalytic converter. This is a direct fit replacement to the stock exhaust unit.

The COBB Tuning catback exhaust is heralded often for its quality, performance, and subtlety. Engineered to be a vehicle specific unit, the catback exhaust uses the highest quality stainless piping and a muffler designed for direct and efficient flow of exhaust to achieve the highest performance while still retaining a stock like appearance and sound level.

The COBB catback exhaust does not deviate from the factory emissions equipment and conforms to the SAE dictated 95-decibel exhaust noise level limit enforced by California, as well as other states in the US. The system is offered with a high flow catalytic converter. This is a direct fit replacement to the stock exhaust unit. This system is modeled after the stock exhaust fitment locations, therefore making it an easy direct bolt on item inclusive of all needed gaskets and hardware.

Constructed purely from 304 Stainless Steel, this system features our cast stainless steel bellmouth to mandrel bent 3" piping, a state-of-the-art metallic substrate catalytic converter, a stock-style flex gasket, our low restriction straight-through muffler that tucks up nicely under the car and ends in a tasteful but not overstated 3.5" double wall tip featuring an etched COBB logo.
