Overview

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 brushed finished 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: 4" Center Inlet /Outlet, 8" Round x 30" L Body Diameter.

OE Fit:
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 4" mandrel-bent 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
