Turbo XS supplies a high-flow catalytic converter pipe crafted for later Subaru turbo platforms, improving flow from the turbo to the rest of the exhaust. This pipe is specified for 2008–2012 WRX/STi applications and also fits certain 2005–2008 Legacy GT models. It serves as a direct replacement cat pipe intended to maintain routing while increasing exhaust throughput.
