The Turbo XS catted downpipe replaces the factory downpipe with a high-flow catalytic converter to improve exhaust flow while retaining emissions hardware where required. It’s offered as a vehicle-specific downpipe for 2002–2007 Subaru WRX and STi and 2004–2008 Forester XT models, providing a more free-flowing path from the turbo outlet to the rest of the exhaust.
