Description
The Flowmaster Signature Series Cat-Back Exhaust System is engineered for maximum sound, performance, and durability for the 2019–2024 and 2026 RAM 1500 (new body) equipped with the 5.7L HEMI engine and factory dual exhaust. This premium system features full brushed 304 stainless steel construction for exceptional corrosion resistance and a high-end appearance.
A large 3.00-inch flanged inlet feeds into Flowmaster’s Signature Series straight-through muffler, designed to deliver an aggressive-to-moderate performance tone with increased power and improved exhaust flow. Dyno testing shows gains of up to 13 horsepower and 13 lb-ft of torque at the rear wheels.
The system is fully TIG welded for greater strength, cleaner aesthetics, and superior heat control. Dual 2.50-inch mandrel-bent tailpipes route cleanly around the factory hitch and spare tire, exiting through the factory bumper cutouts with bold 4.50-inch black chrome 304 stainless steel tips for a premium, custom look.
This bolt-on system utilizes the factory hanger points and connections for a straightforward installation that can be completed at home. All hardware and instructions are included. Designed to fit all wheelbases as well as all cab and bed configurations, in both two-wheel and four-wheel-drive models.
