Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is built for the driver who wants a genuine performance upgrade with an aggressive exterior tone and a moderate interior tone that keeps cab conversation comfortable. Constructed from heavy 16-gauge mandrel-bent stainless steel tubing, this cat-back system is engineered for lasting durability and maximum flow, delivering the deep, purposeful sound Flowmaster is known for without droning you out of the truck.
At the heart of the system is a stainless steel Super 50 Series performance muffler, tuned to blend a deep, aggressive exterior note with a moderate interior tone. It’s the perfect balance for a truck that turns heads at the fuel pump yet stays civil on long drives.
Key Benefits
The 3.00-inch inlet feeds into dual 2.50-inch tailpipes that clear the factory spare tire and give you a choice of exit configurations. Route the pipes straight out the back for a true dual look, or exit out each side behind the rear wheels — an ideal setup for towing. Every system is finished with a pair of 3.00-inch diameter, highly polished 304 stainless steel tips embossed with the Flowmaster name for a clean, unmistakable presence.

Options & Configuration
Because the American Thunder system offers two tailpipe exit locations, you can dial in the look and function that suits your truck — the true dual rear exit for street presence, or the dual side exit for hauling and towing duty. The kit ships as a muffler-included package (Super 50 Series), so the mandrel-bent tubing, hardware, and instructions arrive together for a straightforward, home-driveway installation.
Fitment
This American Thunder cat-back is designed for 2WD and 4WD Standard Cab / Short Bed models only. For the 2007 model year, it fits the Classic body only. Confirm your cab and bed configuration before ordering to ensure a proper fit. Note: this product carries a California Proposition 65 warning.
Designed for an easy fit, the system includes all necessary parts, hardware, and instructions so you can complete the upgrade at home and enjoy the deep, aggressive Flowmaster sound and improved flow your truck deserves.
