Our product development department has taken the guesswork out of adding dual exhaust to your rig and still allow use of the factory spare tire or rear mount hitch, and comes with everything needed for simple installation. More horsepower and torque are a direct result of the massive mandrel bent 4" pipes and improved pulling power and mileage are squeezed out by our high flow muffler assembly.

Available in both stainless and aluminized materials, we have a Cool Duals exhaust system that fits every budget. Bolt on one of the most amazingly designed exhaust systems for the Cummins powered Ram and you too will know that.."We are Performance Exhaust."
