    will I have to bend one of the tubes so it doesn't hit the intermediate shaft?

    Asked by: slow4800
    Tubes should not have to be bent for installation.

    How many o2 sensor fittings are on this kit? Two are visible on the headers themselves but my truck comes with 4 o2 sensors and I cannot see if there are 2 more on the y-pipe.

    Asked by: andrewcollier
    These only have O2's on the headers themselves.
