TurboXS Standard Turboback Exhaust Designed for WRX and STI owners that want a high-flowing system with less noise and a subdued look, the Turbo XS standard muffler turboback offers performance and flow with less noise. The Turbo XS Standard Turboback features Turbo XS’s 4in bellmouth downpipe which tapers to 3in into a 3in high-flow cat or 3in catless race pipe, then runs into a 3in midpipe and terminates in a 2.5in diameter oval muffler with a rolled tip. This is an excellent system for WRX and STi owners looking for a complete after-turbo exhaust solution, but don’t want the noise of the RFL system and want to ditch the stock muffler as well.
