Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is engineered for the driver who wants unmistakable, aggressive sound backed by real Flowmaster performance. Purpose-built for the 2013-2015 Chevrolet Camaro SS (coupes only — not convertibles) and its 6.2L V8, this bolt-on system transforms the way your Camaro sounds and breathes while retaining an emissions-legal, street-ready design. It delivers a deep, aggressive tone inside and out, giving your SS the presence it deserves.
At the heart of the system is a 3.00 in. Scavenger X-pipe assembly paired with proven Outlaw Series mufflers, tuned to produce the aggressive sound level Flowmaster is known for. Every component is fabricated from 3.00 in. mandrel-bent 409S stainless steel tubing for smooth, unrestricted flow and long-lasting corrosion resistance, and the setup finishes in dual tail pipes capped with 4.00 in. quad logo-embossed tips for a bold, finished look at the rear valance.
Key Benefits
Designed as a complete cat-back upgrade, this American Thunder system pairs the free-flowing X-pipe with mandrel-bent stainless tubing to help your 6.2L V8 exhale more efficiently. The Outlaw Series mufflers dial in an aggressive character that carries through the cabin and out the tailpipes, while the emissions-legal design keeps things street-friendly. Note that installing this system will disable the active “dual mode” exhaust function on the Camaro SS.
