As one of the most powerful exhaust systems for A-Bodies with large displacement engines, the Flowmaster “American Thunder” system features heavy-gauge mandrel-bent tubing and Super 40-Series or Super 50-Series mufflers. The tailpipes included are two-piece and install easily. The kit also features an adjustable crossover pipe to fit a variety of applications and has all the hangers and clamps that fit in the factory locations. The 1964-67 kit exits the tailpipes behind the rear wheels pointed at the ground, while the 1968-72 and 1964-72 kits exit out the back at the bumper.
