Give your RAM 1500 the deep, powerful Flow FX exhaust tone with the Flowmaster Flow FX Cat-Back Exhaust System, designed exclusively for 2019–2024 and 2026 RAM 1500 (new body) trucks equipped with the 5.7L Hemi and factory dual exhaust. This system delivers an aggressive to moderate sound profile along with improved exhaust flow and performance.

Built from mandrel-bent stainless steel, the system starts with a 3.00-inch flanged inlet pipe feeding into a straight-through Flow FX performance muffler. From there, dual 2.50-inch tailpipes route cleanly over the suspension, clear the factory spare tire and hitch, and exit through the factory rear bumper dual cutouts. The large 4.50-inch black ceramic-coated 304 stainless steel tips provide a bold, custom appearance.

Installation is simple thanks to the use of factory hanger locations and existing connections—no cutting or welding required. All necessary hardware and instructions are included, making this a true at-home upgrade. The system is compatible with all cab/bed configurations, wheelbases, and both 2WD and 4WD models. Backed by a Lifetime Limited Warranty.
