This American Thunder exhaust system comes as a complete true dual Crossmember-Back exhaust for your 1970-1974 Chevrolet Camaro or Pontiac Firebird with V8 engine. These dual systems feature 2.50-inch mandrel-bent aluminized steel tubing for maximum performance, includes a built-in H-pipe/balance tube flowing into a pair of Slimline 50 Series Delta Flow 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 straight out under the rear bumper and are finished off with 2.50-inch angle-cut brushed stainless steel tips and includes all hangers and necessary hardware for installation. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Covered by our 3-year Limited Warranty.
