The Flowmaster American Thunder Exhaust System is engineered for vehicle enthusiasts seeking performance, aggressive sound, and durability. Dual 2.5-inch mandrel-bent stainless steel tubing flows through the exclusive Scavenger Series X-pipe, providing maximum scavenging for improved exhaust flow and a deep, unique tone. Super 40 Series performance mufflers offer increased internal volume to handle high-flow demands, delivering a moderately aggressive exterior tone while maintaining a comfortable interior sound. The mandrel-bent tailpipes exit through polished 4-inch stainless steel tips under the rear valance, providing a factory-inspired appearance. Designed for easy installation, the system uses factory hanger locations and includes all necessary hardware. Dyno-tuned for maximum performance, it is backed by Flowmaster’s Lifetime Limited Warranty.
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!
