Description
Overview
The Flowmaster American Thunder® Exhaust System Kit is a complete true dual, Crossmember-back exhaust engineered for the classic 1969 Chevrolet Camaro and Pontiac Firebird running a V8 engine. Built for enthusiasts who want their power to be heard, this performance exhaust pairs proven Flowmaster® flow characteristics with a bold, unmistakable tone that suits the muscle-car character of the 302, 307, 327, 350, 396, 400 and 427 platforms.
Constructed from 2.50-inch mandrel-bent aluminized steel tubing, this exhaust system is designed for maximum flow and consistent performance. A built-in H-pipe/balance tube ties both sides together before feeding into a pair of Super 44® series mufflers (muffler part number 942546), producing an aggressive to moderate tone inside and out. Whether you’re searching to shop for exhaust upgrades or comparing a Borla exhaust, Corsa exhaust, or Magnaflow exhaust, this Flowmaster catback-style crossmember-back kit delivers the classic Super 44 sound and Flowmaster reliability.
Key Benefits
Like all Flowmaster® systems, the benefits go beyond sound. This car exhaust setup is built to improve throttle response, power and mileage, giving you a true performance exhaust that looks and sounds the part. The 2.50-inch dual tailpipes exit straight out under the rear bumper and are finished with 2.50-inch angle-cut brushed stainless steel tips measuring 15.20 inches for a clean, aggressive appearance.

Sound & Performance
The Super 44® Series muffler is the heart of this exhaust system, delivering an aggressive to moderate tone that fills the cabin without overwhelming it.

The silver-finished exhaust pipe and mandrel bends keep flow smooth from the crossmember back through the dual exhaust and tail pipes.
