Introducing our new Flow FX® Cat-back exhaust system for the 2019-2024 GM Silverado/Sierra 1500 with the 5.3L engine. The performance exhaust system fits both 2 and 4-Wheel drive models with 148 or 157-inch wheelbases and is manufactured from 409S stainless steel for years of trouble-free service. Features include a 3.00-inch inlet pipe leading into a Flow FX "straight-through" muffler for great sound and maximum performance. Maximum dyno gains of 10 hp and 12 lb.ft of torque at the rear wheels.

The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes detailed instructions and all necessary hardware.
