    I am starting this thread because I would like to get a question answered if some would like to chime in.
    Some have expressed an interest. I say if it floats your boat then try it.
    If one was to drill holes in the end of their stock exhaust to gain a certain level of volume in their exhaust then would this mod affect in any way the engine fuel/air mixture?

    Most certainly it would. Not much, unless they're huge holes, but it'll definately lean out the mixture a tad.

    Anything that promotes freer flowing intake or exhaust will have an effect on the mixtures.

    That's what I'm talking about. Now where do I get an exhaust like that?

    p.s. What's up with the Honda emblems?

    Technically running rich isn't that big a problem -- it's running lean that will kill a motor.

    running rich just causes you to change your plugs often.
