The Flowmaster American Thunder Crossmember-Back Exhaust System, part number 17129, is designed for 1967-1968 Chevrolet Camaro and Pontiac Firebird models with V8 engines. This true dual exhaust system uses 2.5-inch mandrel-bent aluminized steel tubing, a built-in H-pipe, and dual Super 44 Series chambered mufflers to deliver the deep, aggressive to moderate muscle-car sound Flowmaster is known for. Dual 2.5-inch tailpipes exit in the factory locations behind the rear wheels and turn downward below the quarter panels for a clean period-correct layout.
