Description

IMPORTANT NOTICE: Must use 2 1/4 in. offset inlet/center outlet muffler. Designed for use with Hooker Competition headers.

Maximize your exhaust flow and reduce back pressure. Hooker Competition header-back exhaust systems feature large-diameter, 16-gauge steel tubing for improved efficiency, less backpressure, and longer life. Each system is mandrel-bent to maintain a consistent inside diameter for maximum flow. All systems come without mufflers.
