Flowmaster introduces our Force II stainless steel cat-back exhaust system for the 2021-2023 GM Tahoe/Yukon with the 5.3-liter engine. This system uses the Super 40 series muffler for a moderate to mild sound level and increased performance. Mandrel bent 3.00-inch 409 stainless steel tubing allows for maximum exhaust flow and durability. The system uses a larger 3.50-inch polished stainless steel tip for a custom look. This system also has a tuned resonator to control interior sound and maintain driving comfort. Max dyno gains of 6 hp and 7 lb-ft at the rear wheels over stock. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
