This American Thunder® exhaust system comes as a complete true dual Crossmember-Back exhaust for your 1964-1967 GM A-body with a V8 engine. These dual exhaust systems feature 2.50-inch mandrel-bent stainless steel tubing for maximum performance, includes a built-in H-pipe/balance tube flowing into a pair of large case Super 40® mufflers that deliver a moderate to aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The 2.50-inch tailpipes exit at the rear corners of the car and angle down under the rear bumper for a strong muscular look. The system includes all hangers and necessary hardware for installation. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage and is covered by our Lifetime Limited Warranty.
