Wake up your stock exhaust or build your own custom exhaust system with aFe's stainless steel, universal fit MACH Force-Xp muffler. Designed to provide a deep, throaty, powerful sound on acceleration yet maintain a smooth sound at idle. Constructed of 409 stainless steel, the MACH Force-Xp muffler uses a straight through, Y-pipe, perforated core with heat resistant packing to reduce backpressure and maximize exhaust flow for performance and sound improvements over the factory exhaust.
