    If its a generic stage 1 map then it will help with flow but you will need a custom map really.

    as to if you should remove the cats or not is up to you. yearly mot???

    Yea its probably common stage1, have no idea what kind of. When i bought it, it was already mapped, only thing i know is its running on 22psi max boost

    Decat makes sound a lot louder? Nice sound or not?

    a decat alone will do very little in any respect.

    A downpipe and decat however will change the sound, and change some aspect of power delivery.
