This Flowmaster® Flow FX® cat-back exhaust system is for the 2023-2026 GM Colorado/Canyon with the 2.7-liter turbo engine. This system is manufactured using durable 409 stainless steel tubing and features 3.00-inch to dual 2.5-inch mandrel bent pipes for better exhaust gas flow. A Flow FX "straight-through" muffler is used for an aggressive to moderate sound level and maximum performance. Maximum increases on the dyno revealed 14 hp and 15 lb-ft at the rear wheels. This system exits out the side of the truck in front of the rear tire with dual 4.00-inch black ceramic coated tips for added style. The 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.
