The American Thunder® cat-back exhaust system for the 2019-2024, 2026 RAM 1500 (New body) with 5.7L Hemi engine and factory dual tailpipes is perfect for the person looking for a deep powerful exterior sound with all of the performance benefits that you would expect from Flowmaster®. This bolt-on emissions legal system features all mandrel-bent stainless steel tubing leading into a 50 Series™ HD muffler that was originally designed specifically for RAM Hemi engines to deliver maximum power and exterior sound quality, but with a moderately pleasant interior tone at cruising speeds.
