For the person who is looking for a complete Crossmember-Back dual exhaust system for your 1955-1957 Chevy coupes and sedans. This American Thunder® system is manufactured from 2.50-inch mandrel-bent stainless steel for maximum performance and longevity, and includes a built-in H-pipe for a mellow smooth tone eliminating back rap on deceleration. The system includes a pair of Super 40® Series performance mufflers for a deep exterior sound, with a moderate interior tone and dual tailpipes tucked up high for clearance and exit straight out the back under the rear bumper. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Covered by our Lifetime Limited Warranty. Notes: Does Not fit wagons or convertibles.
