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.
