American Thunder Header-Back Exhaust System 1964-1967 GM A-Body V8
FLOWMASTER MUFFLERS 17202 Features:
This American Thunder® crossmember-back exhaust system is a true dual 3.00-inch muscle car system that gives your car a deep aggressive sound. This aluminized steel system is mandrel-bent for maximum exhaust flow and performance. The system includes an H-pipe crossover to balance out the exhaust pressures, add hp and torque, and to help eliminate back-rap on deceleration. The specially selected Super 40® Series performance mufflers are in a large case to handle the high horsepower and provide a deep muscular tone while flowing through the large 3.00-inch tailpipes. The American Thunder systems generally deliver an aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The sound level will depend greatly on the engine and level of modification. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage.
