At idle and around town, the tone is rich and composed. Press the pedal and it comes alive with authority, the kind of sound that makes on ramps, passes, and back roads feel like you are driving an V8, not just getting from point A to point B. It is bold outside the vehicle, but designed for the cabin you live in. At steady highway speed, the system is tuned to help minimize and eliminate in-cabin drone so the ride stays comfortable for long trips, phone calls, and the people riding with you. Even with a full cabin or a trailer behind you, the tone stays controlled.
This dual exit cat back is engineered as a direct bolt on for select late model GM SUVs. Stainless steel construction and premium black chrome tips deliver a clean finish that looks as serious as it sounds. Built for everyday use and backed by the Flowmaster Limited Lifetime Warranty, Flow FX is the upgrade that makes every start up, every merge, and every mile feel like the SUV you paid for.
Your 6.2L SUV is the one you choose when you want the best. Your exhaust should match that feeling. Flow FX gives your 6.2L a deep, premium V8 note that sounds intentional from the first start up, with the restraint and control that makes it right for daily driving.
