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.
Flowmaster is an iconic exhaust brand famous for signature exhaust tone and performance mufflers, as well as complete axle-back and cat-back systems. Built for muscle cars, trucks, and performance builds, Flowmaster systems are designed to improve flow and deliver the sound character enthusiasts chase.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
