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.

Processing & Shipping Overview

Processing occurs before shipping.

Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.

Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.

For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
