Product Description
Upgrade your 2019–2026 Chevrolet Silverado 1500 or GMC Sierra 1500 5.3L with a Flowmaster Flow FX Cat-Back exhaust system, manufactured from durable 409 stainless steel and featuring a Flow FX straight-through performance muffler. These systems are designed for improved exhaust flow, a deep performance tone, and easy installation using factory hanger locations, with each configuration offering a different exhaust routing to suit your truck's existing setup.
Choose from a single-side exit with a 4.50-inch tip, a dual-side exit with dual 4.50-inch tips, or a factory-bezel dual-rear exit designed for trucks already equipped with factory dual exhaust. All three use a 3.00-inch inlet and Flow FX muffler, while the tailpipe configuration differs between the applications.
Redline360 is an authorized Flowmaster dealer and sells only genuine Flowmaster products.
