Upgrade your truck’s exhaust performance and sound with the Flowmaster American Thunder cat-back exhaust system, part number 817843. Designed for 2019-2024 and 2026-2027 RAM 1500 New Body models equipped with the 5.7L Hemi engine, including e-Torque, this emissions-legal system is compatible with factory dual tailpipes and delivers a deep, powerful exterior tone with an aggressive-to-moderate sound level. The system is designed for 2WD and 4WD trucks with select wheelbases and 5.7- or 6.4-foot beds.
Constructed from stainless steel, the Flowmaster 817843 system uses mandrel-bent tubing for smooth exhaust flow and consistent performance. Exhaust gases pass through a 50 Series HD muffler with internals originally developed for RAM Hemi applications, helping provide strong power gains while maintaining a moderately pleasant interior tone during cruising. Dual tailpipes route cleanly around the factory spare tire and exit through the original rear bumper cutouts for a finished, factory-style appearance.
Installation is designed for the home mechanic and uses factory hanger locations, helping simplify fitment without extensive modifications. The kit includes the required components, hardware, and installation instructions. Large black ceramic-coated exhaust tips provide a durable finish and a distinctive appearance, while the stainless-steel construction is built for long-term use. Flowmaster backs this American Thunder system with a Lifetime Limited Warranty. This system does not fit RAM 1500 Classic body models or trucks equipped with a factory single-exit tailpipe.
