Power, quality and sound is what this Large Bore-HD series down-pipe back exhaust system offers. 4" mandrel-bent 409 stainless steel tubing and high-flow muffler are less restrictive keeping exhaust pulses flowing smoothly for increased power gains. A 6” high-temp. black powder coated stainless steel exhaust tip completes the look. Factory style hangers, quality band clamps and all necessary hardware ensure a quick install and long-lasting exhaust that looks as good as it performs.
Flow and Performance:
This Large Bore-HD exhaust system is constructed of 4" mandrel-bent 409 stainless steel tubing for maximum flow and longevity. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lower EGT's.
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. Stamped with an aFe POWER logo for an aggressive style. Muffler Specifications: 4" Center Inlet /Outlet, 8" Round x 24" Length Body.
6" Diameter Black Tip:
This system is finished off with a 6" high-temp. black powder-coated slash cut tip. A unique laser-cut aFe Power logo plate is riveted on for a custom, quality finish.
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.
