FLO FlowFX Muffler

Designed for select late model GM SUVs, this system is engineered for straightforward installation using factory style mounting points. It is built from stainless steel for long term durability and backed by the Flowmaster Limited Lifetime Warranty. If you want the emotional payoff of better sound with the practicality of an easy install, Flow FX is the right move. Your 5.3L feels a little too quiet for what it is, this is the upgrade that changes the experience without changing your routine. The Flow FX Direct Fit Muffler System delivers a deeper, more confident V8 tone with the simplicity and value of a direct fit replacement. It is the perfect first step for drivers who want a meaningful change without the complexity of a full system. Start it up and the sound has more presence right away. Drive it around town and you get a richer tone that feels premium, not obnoxious. Tip into the throttle and the SUV finally sounds like it matches what it can do. Then, when you settle into steady highway speed, the sound profile is tuned to help minimize and eliminate unwanted in-cabin drone so your daily drive stays comfortable. It is the kind of upgrade that your passengers can live with and you will appreciate every time you drive. Flowmaster Flow FX Direct Fit Muffler.
