Flowmaster® proudly presents the American Thunder® dual exhaust system tailored for 1967-1974 Chevrolet Camaro, Pontiac Firebird, and 1968-1974 Chevrolet Nova models. Crafted entirely from stainless steel, this exhaust system showcases the exclusive 80 Series™ Crossflow muffler design, coupled with mandrel-bent dual 2.50-inch pipes that include an H-pipe crossover. The result is a deep, smooth tone with minimal back-rap on deceleration. The dual 2.50-inch stainless steel tailpipes contribute to a rich, resonant sound and optimal performance.
This 409S stainless crossmember-back system is engineered to provide a moderate tone both inside and outside these classic muscle cars. The innovative crossflow design strategically places the muffler behind the rear axle, maintaining full ground clearance beneath the vehicle while delivering the performance advantages of a complete dual exhaust system. The package includes all necessary components, hardware, and detailed instructions. Like all Flowmaster stainless steel street products, it is backed by our Limited Lifetime Warranty.
