    3 Top Rated Questions

    Will this fit with the kooks 1 3/4 in long tube headers MPN# 11412200? The description on the page for the headers states they only fit with the x pipe.

    • The Kooks GREEN Catted H-Pipe - 3 in. to 2.75 in. should work with any of the Kooks 3" long tube headers. The headers you listed have a 3" collector, so they should work with this H-pipe.

    • The Kooks GREEN Catted H-Pipe can be attached to the OEM catback exhaust, but Kooks Long Tube Headers will be required.
