Details

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.

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.
