Flowmaster® is proud to introduce our American Thunder® dual exhaust system for 1967-1974 Chevrolet Camaro, Pontiac Firebird and 1968-1974 Chevrolet Nova's. This all stainless steel exhaust system features our exclusive design 80 Series™ Crossflow muffler, all mandrel-bent dual 2.50-inch pipes including an H-pipe crossover for a deep smooth tone that also minimizes any back-rap on deceleration. The dual 2.50-inch stainless steel tailpipes provide a deep rich sound and optimum performance. This Crossmember-Back 409S stainless system gives these classic muscle cars a moderate tone inside and out. Using the crossflow design, this exhaust places the muffler in the factory location behind the rear axle retaining full ground clearance under the car while offering all the performance benefits of a full dual exhaust system. The system includes all parts, hardware and illustrated instructions, and like all Flowmaster stainless steel street products, it includes our Limited Lifetime Warranty.
Fits 1967-1974 Chevrolet Camaro, Pontiac Firebird with V8 engine. 2.50 inch Stainless Steel - Moderate sound
Convertible models require 3/8-inch of shims on the factory X-brace for clearance of the exhaust tubing.
