Description
Overview
The Flowmaster Chevrolet, GMC (5.3) Exhaust System Kit is a direct bolt-on cat-back exhaust system engineered for select late-model GM SUVs equipped with the 5.3L engine and 4WD. Part of Flowmaster’s Flow FX series, this complete exhaust system pairs a Flow FX muffler with mandrel-friendly piping to deliver a stronger, sport-focused look and an improved exhaust note without the complexity of a custom build. When you shop for exhaust upgrades that install with confidence and hold up season after season, this Flow FX catback exhaust is built to fit cleanly and perform.
Constructed from durable 409 stainless steel with a 16-gauge pipe wall, this performance exhaust is designed to resist corrosion and endure the demands of daily driving and towing. The system uses your factory hangers for a straightforward, direct-fit installation, so there is no need to modify or fabricate new mounting points. The result is a car exhaust and SUV exhaust system that bolts on and looks factory-finished from the first drive.
Sound & Style
The Flow FX muffler is tuned for a Moderate/Mild sound level, giving your truck or SUV a purposeful, refined tone that is aggressive under throttle yet comfortable at cruise. A dual exit layout finishes the rear with premium tips and an embossed Flowmaster logo, delivering an angled 4.00-inch tip presentation that upgrades your stance every time you walk up to it. This is the sound and look your SUV should have had from day one.
