The Flowmaster American Thunder Dual Rear Exit Exhaust System is designed for drivers who want a bold, aggressive exhaust tone combined with reliable performance. Constructed from 16-gauge mandrel-bent stainless steel tubing, this cat-back system flows into a dual-outlet 50 Series HD™ performance muffler that provides deep exterior sound while minimizing interior cabin drone.

The system features dual 2.50-inch mandrel-bent tailpipes finished with polished 4.00-inch stainless steel tips, exiting straight out the back under the bumper for a muscular, factory-integrated appearance. Tailpipes are designed to clear the spare tire, maintaining full functionality while improving flow and style.

Installation is straightforward, reusing the vehicle’s factory hanger locations and including all necessary hardware and detailed instructions for a quick at-home upgrade. Backed by Flowmaster’s Lifetime Limited Warranty, this system delivers long-lasting quality, enhanced performance, and aggressive styling.
