The Kooks catted H-pipe for 2005–2010 Ford Mustang GT 4.6L 3V is a direct-fit midsection that requires Kooks headers. Sized 2.50in x 2.50in OEM out, the H-pipe helps tune exhaust flow between sides while maintaining factory-style connections. The supplied catted sections are intended for non-forced-induction use and are designed to mate cleanly with Kooks header systems.
