    The Flowmaster® American Thunder® Axle-back system for the 2016-2024 Camaro SS & ZL1 with the 6.2L engine, is perfect for the person looking for a powerful and very aggressive sound quality in Track mode, while maintaining a deep mellow tone for everyday driving. This kit features tandem 40 Delta Flow™ Series mufflers for daily driving, along with a pair of our race-proven Outlaw® mufflers that actually increase the open exhaust sound when in Track mode. The system is finished off with large quad 4.00-inch polished stainless steel tips replicating the factory quad NPP exhaust look. Includes functional exhaust valves to work with the O.E. actuator motors to select between sound levels. The exhaust system is full stainless steel and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit on both coupe top and convertible models with the factory NPP option (identified by quad tips.) The system includes all necessary parts and hardware for installation. Note: Be sure to check out our Scavenger Series® X-pipe, #81083 for 6-spd manual with factory MDS valves, designed to replace the factory mid-pipe and the flattened section of the factory tubing.
