Enhance your 2021–2026 GM Tahoe or Yukon 5.3L with the Flowmaster Force II Cat-Back Exhaust System. Designed for a moderate to mild exterior tone while keeping interior cabin noise comfortable, this exhaust system improves performance and delivers the quality Flowmaster sound you expect.

Constructed from durable 16-gauge mandrel-bent 409 stainless steel tubing, the system flows into the Super 40 Series muffler, providing a refined, smooth tone with increased performance. The exhaust exits through a single 3.50-inch polished 304 stainless steel tip for a clean, custom look. A tuned resonator is included to reduce interior drone and maintain driving comfort.

The system installs easily using factory hanger locations and comes with all necessary hardware for at-home installation. Flowmaster’s Force II Cat-Back Exhaust delivers up to 6 hp and 7 lb-ft of torque gains at the rear wheels, backed by a Lifetime Limited Warranty for long-term reliability.
