The CORSA Xtreme valved cat-back exhaust for the Shelby GT500 Predator V8 uses 3.0 in 304 stainless steel tubing, a Double Helixx dual crossover X-pipe, and straight-through mufflers. CORSA cast valve assemblies retain the factory active exhaust function, running over 10 dB louder than stock with the valves open while No Drone RSC technology keeps the cabin quiet at cruise. It exits the rear through twin 5.0 in dual-wall polished straight-cut Pro tips and bolts on in about an hour.
