AFE 4" Exhaust System



Since diesel engines are a compression ignition engine and modern diesel-powered vehicles are turbocharged, the more air you pump in, the more power you generate. However, which turbocharged diesel, it is very important to get the hot exhaust out or the Exhaust Gas Temperature (EGT) rise to critical level that could damage the turbo itself. Most OE manufacturers offer a restrictive 3 1/2" exhaust system which is fine for normal every day city or highway driving. But you bought a diesel truck for its towing or work capabilities, didn't you? If so, you want more power to go up that grade towing your boat, trailer or tools.

Getting the air in will give you more power. Getting the air out will give you more power. When you get more air in and out at the same time, you get a lot more power. With our 4" exhaust systems are mandrel bent aluminized steel which eliminates the sharp bends and kinks that the factory stock exhaust systems have. The aluminized steel resists corrosion as well as stainless steel but is priced more economically.

Our large 8" diameter straight flow through mufflers do a good job of letting the air out as well.

The 5" diameter Exhaust tips finishes up the entire system for a nice throaty sound and appearance enhancement.

Our entire systems comes with adjustable clamps, muffler and sectional tubing for easy installation whether you have a standard, extended or crew cab vehicle. (Exhaust tips sold separately)
