This Flowmaster® American Thunder cat-back exhaust system is for the 2021-2026 Ford F-150 with the 2.7, 3.5 or 5.0-liter engine or the 3.5L PowerBoost models. This system is manufactured using durable 409 stainless steel tubing and is mandrel bent for better exhaust gas flow. Super 40 Series muffler is used for an aggressive to moderate sound level and maximum performance. Maximum increases on the dyno revealed 18 hp and 14 lb-ft at the rear wheels. This system uses dual 4.5-inch black ceramic coated tips for added style. This system uses all the existing factory hanger locations and includes installation instructions and all necessary hardware for an easy installation that you can do at home. Backed by Flowmaster's Lifetime Limited Warranty.
