    3 CM downpipe

    some information

    - OE turbo manifold
    - HX35W
    - Roastin Holset adaptor
    - 3" vibrant turbo back - welded to a T25 DP

    The vibrant system bolts to the stock catalitic converter mount but will not directly bolt to the HX, hacking is out of the options due to time constrictions.

    Roastins HX adaptor was designed to work with the CM system, so what i need to know is if the CM downpipe bolts up to the OE catalic convert mount as seen below.

    Yes, I put the magnaflow high flow cat, but its the same flange as the stock converter....3"…cat back is 2.5" though…so in your case you should be fine
