Flowmaster 17129 American Thunder Crossmember-Back Exhaust System

This American Thunder system is specially designed for 1967-1968 Camaro and Firebirds and is perfect for the person looking for a complete Crossmember-Back dual exhaust system. With an easy-fit in mind, this exhaust system is manufactured as a true dual exhaust using 2.50-inch aluminized steel tubing throughout, includes a built-in H-pipe design and delivers improved throttle response, power with a deep muscle car sound. The mandrel-bent tubing flows into a pair of Super 44 mufflers with 2.50-inch tailpipes exiting in the factory location behind the rear wheels pointing down just below the quarter panel. The system delivers a moderate to aggressive interior and exterior tone that's suited for the enthusiast who wants their performance to be heard. Designed for an easy fit, these systems include all necessary parts, hardware, and instructions. If you prefer Stainless steel construction, check out optional system# 817129. Notes: Fits convertibles by spacing down the factory convertible body brace by approximately .375-inch, or you can replace the factory body brace with a Hotchkis Performance body brace part #1404.
