The Flowmaster American Thunder Crossmember-Back Exhaust System is a high-performance dual exhaust upgrade designed for classic American muscle cars. Constructed with aluminized steel, it features mandrel-bent dual 2.50-inch head pipes with a built-in H-pipe crossover, enhancing exhaust flow and sound quality. The system incorporates Flowmaster’s exclusive 80 Series Crossflow performance muffler, which is positioned high behind the rear differential to deliver a deep, rich exhaust note while optimizing performance and durability. This system provides a moderate tone both inside and outside the vehicle, making it suitable for enthusiasts seeking a balance of sound and performance. All necessary hardware, parts, and illustrated instructions are included, backed by a 3-year Limited Warranty. An optional stainless steel version with a Lifetime Limited Warranty is also available.

This exhaust system is specifically designed to fit 1967-1974 Chevrolet Camaros and Firebirds, as well as 1968-1974 Novas. It is a direct bolt-on replacement for the factory system, intended for street use and performance upgrades. Note that it does not include manifold downpipes or header reducer cones. Convertible models may require additional shims or a specific brace for clearance. The kit includes all components needed for installation, making it suitable for restoring or upgrading these classic vehicles for improved sound and performance.
