Flowmaster FlowFX Cat-back Exhaust System 2019 GM Silverado/Sierra 1500 5.3L

By: Flowmaster02/12/2019 < Back to Blog Home

Flowmaster’s FlowFX Cat-back exhaust system is designed for the 2019 GM Silverado/Sierra 1500 trucks (new body style) with 5.3L engine and factory dual exhaust. This bolt-on system is manufactured using durable 409 stainless steel throughout and features a 3.00-inch inlet pipe leading to a single inlet/dual outlet FlowFX straight-through muffler for a deep, moderately aggressive sound and maximum performance. The dual 2.50-inch mandrel bent tailpipes are custom routed to clear the factory spare tire and tow hitch without any clearance issues and exit out through the OEM exhaust bezels in the bumper, retaining the factory dual exhaust appearance. This system utilizes factory hanger locations, includes installation instructions, and all necessary hardware for an easy at home installation.


Note: Fits 2WD and 4WD models. Does not fit crew cab 2WD with 2-piece driveshaft. Does not fit 2019 LD/classic body style or trucks with factory single exhaust system.
