This American Thunder® exhaust system comes as a complete true dual headers-back exhaust for your 1964-1967 GM A-body with a V8 engine. These dual exhaust systems feature 2.50 in. 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 in. 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.
