    The MHR team2 kit is a pretty extreme kit...the crank cases are gonna have to be matched to the barrell at the least to get anywhere near the power potential
    that kit can produce ;)

    Tell us how that pipe runs. It looks quite agressive in the convergent cone. I think it will hit very hard but be quite narrow.

    youll find its very quiet at 1st...and a bit tinny sounding.

    but it does get less tinny as the baffles oil up a bit over time ;)

    I didnt mind the sound...more stealth like...I could creep up on the chavs :pimp:

    inside the box theres an air slot where the air passes from one side of the filter element to the other...i made this bigger..

    Then i took the trunking off the front of the box and made the inlet hole a little bigger...and fitted a slightly larger smoother flowing plastic inlet elbow i found at work..

    i then deburred the outlet hole that the rubber that joins the carb to the box itself fits onto ;)
