Wake up the power and performance of your 2009–2024 RAM 1500 Classic equipped with the 4.7L or 5.7L Hemi engine with the Flowmaster American Thunder Cat-Back Exhaust System. Designed for an aggressive yet refined exterior tone with minimal in-cab drone, this system improves performance and delivers the iconic Flowmaster sound.

The system is fully constructed from 16-gauge mandrel-bent stainless steel tubing flowing into a 50 HD Series performance muffler. The muffler features a single inlet with dual outlets for optimized exhaust flow and sound quality. Dual 2.50-inch mandrel-bent tailpipes are finished with a pair of 3.00-inch polished 304 stainless steel tips, with your choice of exit style: dual side behind the wheels for towing applications or straight rear under the bumper for a muscular look.

This cat-back system installs using factory hanger locations and includes all necessary hardware for a simple at-home installation. Designed to connect after the factory catalytic converter, it’s engineered for durability, sound, and performance.
