The Flowmaster American Thunder SS Exhaust System is a complete true dual Crossmember-Back exhaust designed for 1968-1972 GM A-body vehicles equipped with a V8 engine. Constructed with 2.50-inch mandrel-bent stainless steel tubing, it maximizes performance by enhancing exhaust flow and durability. The system features a built-in H-pipe/balance tube that directs exhaust into large case Super 40 mufflers, producing an aggressive tone both inside and outside the vehicle. The 2.50-inch tailpipes exit at a slight downward angle beneath the rear bumper, giving a muscular and performance-oriented appearance. All necessary hangers and hardware are included for straightforward installation. As with all Flowmaster systems, this exhaust improves throttle response, increases power and fuel efficiency, and is backed by a Lifetime Limited Warranty.

Designed specifically for 1968-1972 GM A-body models with V8 engines, this exhaust system serves as a direct replacement for the factory setup. It is ideal for enthusiasts seeking a performance upgrade with a bold sound for street use. The system is a bolt-on installation that includes all components needed for a complete upgrade. Suitable for daily driving and performance applications, it enhances vehicle sound and performance while maintaining a high-quality stainless steel construction for long-lasting durability.
