The CORSA Xtreme cat-back exhaust is a 3.0 inch 304 stainless steel system that exits to a single passenger side with twin 4.0 inch dual-wall Pro Series tips in a Black PVD finish. Xtreme is CORSA's loudest sound level, delivering an aggressive cold start and up to 20 decibels more than stock under acceleration, while patented Reflective Sound Cancellation (RSC) technology keeps the cabin drone-free at cruise. The free-flowing design outflows the factory exhaust by 80 percent and bolts on with no cutting or welding.
