For the enthusiast who wants the most from their vehicle. Engineered and dyno-tested to give you improved acceleration, maximum hill climbing, towing and passing power.

Our best performing exhaust system produces maximum torque and horsepower gains at low-end (1800 to 3000 RPMS ) with a deep aggressive tone.

Exits behind the rear tire near stock location. Quieter in the cab than any other performance exhaust.

Fuel economy may improve as your engine becomes more fuel-efficient. Ideal system for towing. Heavy duty enough for off-road use.
