The CORSA valves work with the GT500's factory solenoids and active-exhaust controls.How loud is the system?CORSA describes an Xtreme-to-Touring active range with an approximately 11-decibel difference across the vehicle's exhaust modes.What are the exhaust tips made from?The four 5-inch outlets use black carbon-fiber outer construction with stainless-steel inner cones.Is welding required?The system is designed as a bolt-on cat-back. CORSA does not recommend welding its exhaust systems because welding prevents adjustment and can affect warranty coverage.What warranty applies?CORSA lists lifetime exhaust coverage and five-year valve coverage under its current warranty terms.Installation Instructions Allow the exhaust to cool completely, raise the vehicle securely, and disconnect the factory active-exhaust wiring before removal. Remove the factory cat-back while retaining the valve solenoids, wiring, hangers, and any factory connection hardware called for by the vehicle service procedure. Assemble the CORSA X-pipe, muffler sections, valves, and black carbon-fiber tip assemblies loosely so alignment can be adjusted. Transfer and connect the factory valve solenoids, then align the pipes, hangers, and four outlets with adequate chassis and bumper clearance. Tighten all hardware to the current CORSA and Ford service specifications, cycle every factory exhaust mode, and check for leaks or contact after the first heat cycle.
