The dual exit layout finishes the rear with a stronger, sport focused look and premium black chrome tips, giving your SUV an stance every time you walk up to it. Engineered as a direct bolt on cat back for select late model GM SUVs, Flow FX is made from stainless steel and built to fit cleanly, install with confidence, and hold up season after season. It is backed by the Flowmaster Limited Lifetime Warranty, because this is not a temporary upgrade. It is the sound your SUV should have had from day one.

| Description_MKT |
Your SUV does it all. Morning commute. Kid duty. Weekend towing. Long highway miles. Flow FX is built for that real world. It gives your 5.3L the deep V8 character you want on cold start, when you hit the gas, and stays controlled when you settle in for the drive. |
| Description_MKT |
Turn the key and you get a confident, refined start up that sounds capable, not chaotic. Rolling through town, the tone is present and premium, not raw and raspy. Step into it on an on ramp, a two lane pass, or a pull away from a stoplight and Flow FX delivers the bold sound that reminds you why you chose a V8 in the first place. When the pace steadies, the system is tuned to help minimize and eliminate unwanted in-cabin drone, so the cabin stays a place for music, conversation, and miles that do not feel like work. You hear the upgrade outside the vehicle, but you can still live with it inside. It is a sound that fits premium interiors and real passengers. |
