  • No, this Kooks mid pipe is made for Kooks long tubes only


Are there replacement high flow cats for this Kit (Item #65508 MPN# 11313200)? Kooks or otherwise, that would fit. (Part Numbers would be greatly appreciated). Thanks in advance

  • The Kooks Catted X-pipe (05-10 GT w/ Long Tube Headers) will be a great X pipe for your car. We only carry the Kooks off-road and catted X-pipe. Both will be the same just one will not have any cats making it louder.


Catted Is the catalytic converter necessary for a daily driver? I don't know whether to get this or the offroad X-pipes

  • Most states need catalytic converters for smog and registration.

    Had an original early design kit without brace on the x, so it has cracked on the weld. Got this one as replacement and it is a new design now, giving a piece of mind about longevity.
