    If you do all those mods to the motor I don't think it should be too big. If you weren't I would say go 2.5"

    Should be fine. Might lose a tad low end torque. You will gain top end hp though.

    Loud and deep. Personally would recommend going with single 3" for performance reasons, but to each his own.
