FlowFX Cat-Back Exhaust System

This Flowmaster(R) FlowFX(R) cat-back exhaust system for the 2019-2023 GM 1500 trucks with the 2.7-liter turbo engine and a 147-inch or 157-inch wheelbase. This system is manufactured using durable 409 stainless steel throughout and features single 3.50-inch to dual 2.50-inch mandrel bent pipes for better exhaust gas flow, and a FlowFX "straight- through" muffler is used for a moderate sound level and maximum performance. Maximum increases on the dyno revealed +9 hp and +12 lb-ft at the rear wheels. This system exits out both sides, behind the rear wheels with 4.50-inch black ceramic tips for added style and a custom look. 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.
