The APR Cat-Back Exhaust System is a direct bolt-on replacement hand built from T304 stainless steel with argon back-purged TIG welding throughout. Mandrel-bent 3 in piping runs into a cast splitter that feeds quad 2.5 in tailpipes, while two straight-through brushed mufflers and a Helmholtz resonator smooth the note to a deep growl without adding restriction. Cast valve housings accept the factory electronic valve actuators, so OEM valve operation is retained, and OEM style slip clamps with Torca AccuSeal T304 tip clamps hold the low-profile system securely in place. Removable 4 in polished slash-cut tips finish the system, and the larger diameter piping adds no weight over stock.
