Description
Overview
The Flowmaster® Flow FX Exhaust System Kit is a complete cat-back exhaust system engineered for 1996–1999 Chevrolet and GMC 1500 trucks equipped with the 5.7-liter engine. Built to bolt right into place using the existing factory hanger locations, this performance exhaust upgrade replaces the restrictive stock system with mandrel-bent tubing and a purpose-built Flow FX muffler for stronger flow, a more aggressive tone, and a clean, finished look under your truck. If you’ve been searching to shop for exhaust that delivers real gains without complicated modifications, this Flowmaster catback exhaust is a straightforward, home-installable answer.
Every tube in this exhaust system is manufactured from durable 409 stainless steel and mandrel bent to preserve diameter through the curves, promoting better exhaust gas flow from the muffler back. The Flow FX Series muffler is included and tuned for an aggressive-to-moderate sound level, giving your car exhaust a deeper, purposeful voice at wide-open throttle while staying comfortable at cruise. This is a CARB (California) compliant system, so it’s built to keep you legal in emissions-tested regions.
Key Benefits
As a true catback exhaust, the kit arrives with everything you need for a confident driveway install. It uses all of the existing factory hangers, includes installation instructions, and comes with the necessary hardware, so you can complete the job at home without cutting or fabricating custom exhaust pipe. The dual tail-pipe design routes to a dual outlet muffler with a center inlet, and the tips exit on the passenger side just in front of the rear wheel for a purposeful, factory-plus appearance.
