High Flow 409 Stainless Steel Muffler:
This 409 stainless 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 409 stainless 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: 5" Center Inlet /Outlet, 8" Round x 24" L Body Diameter.
OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.
Flow and Performance:
This Large Bore-HD exhaust system is constructed of 5" mandrel-bent 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
7" Diameter Polished Intercooled Tips:
Finishing off the exhaust is a 7" diameter, high luster polished, stainless steel slash cut tip with intercooled vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut black powder-coated aFe Power logo plate is riveted on for an aggressive style.
