This is NOT an OEM fit. Pipe has bend in it that makes it impossible to install without modification. Has no port for Oxygen sensor either.

This part isn't supposed to have a port for the O2 sensor. This is the resonator assembly, not the catalytic converter and flex pipe assembly. The O2 sensor goes before the second catalytic converter.
