The Flowmaster American Thunder SS Exhaust System is a complete true dual Crossmember-Back exhaust designed for 1964-1967 GM A-body vehicles equipped with a V8 engine. Constructed with 2.50-inch mandrel-bent stainless steel tubing, this system maximizes performance by improving exhaust flow and throttle response. It features a built-in H-pipe/balance tube that directs exhaust into a pair of large case Super 40 mufflers, producing a moderate to aggressive tone both inside and outside the vehicle. The dual tailpipes exit at the rear corners, angling down under the bumper for a muscular, performance-oriented appearance. All necessary hardware and hangers are included for straightforward installation. Like all Flowmaster systems, it enhances power, mileage, and responsiveness, backed by a Lifetime Limited Warranty.
This exhaust system is specifically designed for 1964-1967 GM A-body models with V8 engines, serving as a direct replacement or upgrade for stock exhausts. It is ideal for enthusiasts seeking a performance sound and improved exhaust flow for street use or spirited driving. The kit includes all components needed for installation, with tailpipes exiting at the rear corners for a clean, aggressive look. Suitable for street performance applications, this system provides a durable, high-quality upgrade to enhance vehicle sound and performance while maintaining a factory-like fitment.
