The Kooks 1-7/8" x 3" stainless steel long-tube headers for 2016+ Chevrolet Camaro SS include 3" x 2-3/4" OEM high-flow catted connection pipes to mate to the factory system. These long-tube headers are built for improved exhaust scavenging and must be paired with the included connection pipes; factory exhaust trimming is required for installation. Standard race cats are not for use in forced-induction applications.
