Description
The Kooks 22604181 3″ Connection-Back Exhaust System is engineered for Camaro SS and ZL1 owners running Kooks long tube headers who want increased performance and a deeper, more refined sound while keeping their factory rear mufflers. This system replaces the factory mid-pipes and rear pipes with premium 3-inch 304 stainless steel tubing, dramatically improving exhaust flow from the header collectors back to the stock mufflers.
This premium system includes a 3-inch X-pipe for enhanced exhaust scavenging, stronger midrange torque, and a smoother, more aggressive exhaust tone. The system tapers to a 2.75-inch OEM-style outlet, allowing seamless connection to the stock Camaro SS/ZL1 mufflers—retaining factory NPP functionality (where equipped) and OEM sound control while adding performance.
Perfect for drivers seeking a performance increase without going to a full cat-back or muffler-delete system, this Kooks connection-back exhaust offers a deep, muscular tone, reduced restriction, and improved throttle response while maintaining a comfortable street sound level.
