The aFe Universal fit Aluminized Steel Performance Muffler is designed to provide a deep, throaty, powerful sound on acceleration, but maintain a smooth sound at idle. This muffler is constructed of brushed finished aluminized steel and uses a straight through perforated core with heat resistant packing to reduce backpressure and maximize exhaust flow. You will see increased performance and improved throttle response over the factory exhaust. Also featuring a stamped aFe Power logo for an aggressive style. Muffler Specifications: 3-1/2" Center Inlet /Outlet, 16"L Body Diameter. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
