This 3" stainless steel center exhaust section includes a 3" high-flow catalytic converter to replace the stock unit. There's even a bung to mount your rear oxygen sensor, so your ECU will be happy and not throw catalytic-converter-related error codes.
Mates up perfectly to the TurboXS Super-Huge Downpipe and 3" mid pipe (pictured alongside the cat section, above); will not fit up to factory exhaust parts. You MUST have the TurboXS Super-Huge Downpipe and 3" mid pipe to use this center section. Or, if you want to use another brand of cat-back exhaust with it, you'll be doing some fabricating to join the pipes together.
