This Kooks OEM-style catted X-pipe fits 2005–2010 Ford Mustang GT 4.6L 3V applications and must be used with Kooks headers. The 2.50in x 2.50in catted midsection complements long-tube header systems and uses OEM-sized connections. Standard race catalytic sections supplied are noted as not for forced-induction use; the assembly is intended to integrate with Kooks header designs for improved flow.
