Turbo XS Stealthback Exhaust (Catted) 02-07 WRX & 04-07 STI

For WRX & STi owners looking to keep their stock muffler, or use a different axle-back, the Turbo XS Stealthback is the exhaust for you. This system includes Turbo XS's 4" bellmouth downpipe, which tapers to 3" into a 3" high-flow cat (or racepipe in the catless version), and then into a 3" midpipe. Turbo XS's cat to downpipe connection features an OEM style ball-and-socket design with a donut gasket, to allow exhaust movement while maintaining a tight seal.
