The CORSA Xtreme axle-back exhaust replaces the factory rear section with 2.75 in 304 stainless steel tubing, dual rear exits and quad 4.5 in polished Pro-Series dual wall slash cut tips. It plugs directly into the factory Dual-Mode NPP valve actuators, giving over 17 dB of difference between valves open and closed. Reflective Sound Cancellation (RSC) technology delivers an aggressive Xtreme note under acceleration with no drone at cruise in any valve position or mode. CORSA rates it at +4 hp, 23% more flow than stock and 4 lbs lighter than the factory exhaust; it bolts on with no welding and is made in the U.S.A.
