Flow and Performance:
This ATLAS exhaust system is constructed of 5" mandrel-bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
High Flow Alumizined Muffler:
This 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 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: 5" Center Inlet /Outlet, 7" Round x 24" L Body Diameter.
