    umm we need to know mods.
    i say as a rule of thumb

    very build N/A motor/or small build with nitrous 2.5"
    turbo or built with Nitrous=3"
    small-medium build 2.25"

    tell me what ur mods are, and future plans and i can better tell u the size.

    2.5 is good for a pretty powerful NA motor for our hondas. Turbo 3inch for us, and higher for others...

    2.5", if hes lowly modded now he can always upgrade and not be choked off.

    also, on a lightly modded car, 2.5" is more top end, 2 1/4 is more bottem end.
