GM 5.3L 2007 1/2-2023 Truck Cat Back Dual Exhaust Kits
Make your GM 5.3L sound and perform the way it should by increasing the exhaust flow and enhancing overall power.
More power means you don't have to mash the go pedal as hard and as a benefit, we have seen a 2-4 mile per gallon increase on the highway.
MPI Turbo series mufflers are going to have a nice mellow sound, with a slightly higher noise level over stock with a lower tone making it sound like a truck instead of a Hoover vacuum.. MPI Performance series mufflers are going to be more aggressive sounding with more growl at the tailgate and a bit more sound in the cab. Either muffler choice is guaranteed no droning.
Note: All our kits are produced for the longest wheelbase available for this truck. You may need to trim your kit and the included instructions provide all the necessary measurements to make it a perfect fit.
Reinforced for Heat and Corrosion
Our Aluminized Steel Tube's raw material undergoes a continuous hot-dip process, building a coating across every millimeter of the surface.
Hot-dipping results in a tight metallurgical bond between layers of an aluminum-silicon alloy and the tube’s steel core.
The final aluminized tube possesses a combination of enhanced properties: the strength of steel sheathed in the corrosion resistance of aluminum and the heat protection of aluminum-silicon alloy. It also performs quite nicely against exposure to salts.
