Description
Overview
The Flowmaster American Thunder Axle-back Exhaust System is engineered to wake up the 5.7L HEMI in the 2019-2024 and 2026 (New Body) RAM 1500. Built from durable stainless steel, this axle-back kit swaps out the restrictive factory setup and replaces the small 2.25-inch tailpipes and resonators with larger 2.50-inch mandrel-bent tubing for smoother flow and a more aggressive attitude. It’s part of Flowmaster’s proven American Thunder series, delivering a moderate sound level that adds real bark without droning your daily drive.
Key Benefits
Upgrading to larger mandrel-bent tubing helps improve exhaust flow over the smaller factory tailpipes, while the non-resonated design lets more of that iconic HEMI tone through. The dual tailpipes exit in the stock location and utilize the factory hanger points, so you get a clean, OE-style fitment without the guesswork. Every kit is finished with large 4.50-inch black ceramic coated 304S stainless steel tips featuring an embossed logo, giving your RAM a bold, purposeful look at the rear bumper.

The Kit & Configuration
This is a complete axle-back package designed for a quick and easy at-home installation. Because it mounts to the factory hangers and exits in the stock position, most enthusiasts can complete the job with basic tools and the included hardware and instructions. The silver pipe color and black ceramic coated tips create a refined contrast, while the American Thunder muffler tuning dials in that moderate, street-friendly sound. Note that a muffler is included in the system though no separate replacement muffler part number is offered, and no heat shield is included.
Fitment
This American Thunder axle-back kit fits the 2019-2024 and 2026 (New Body) RAM 1500 equipped with the 5.7L HEMI engine. It is compatible with 2WD and 4WD trucks and all wheelbases, with one exception: it will not fit trucks equipped with the factory single tailpipe. Please confirm your truck has factory dual tailpipes before ordering.
