Description
The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2019–2024 and 2026 RAM 1500 (New body) trucks with 5.7L Hemi engines and factory dual tailpipes. This system delivers a deep, powerful exterior sound with a moderately pleasant interior tone, combining signature Flowmaster performance with a daily-drivable comfort.
Constructed with mandrel-bent 409 stainless steel tubing, the system flows through a 50 Series™ HD muffler engineered specifically for RAM Hemi engines. Dual 3.00-inch tailpipes clear the factory spare tire and exit through large 4.00-inch black ceramic-coated tips, filling the factory bumper cutouts for a clean, custom appearance. Installation is simple using all factory hangers, with all hardware and instructions included. Backed by Flowmaster’s Lifetime Limited Warranty, this cat-back system is the ultimate upgrade for RAM 1500 owners seeking both style and performance.
