awhile back I read something, maybe on expresslymopeds or MRA, I can't remember now, but anyway it was something to the effect of, rather than cutting the whole express exhaust in half and gutting all that shit out, you can achieve the same results by drilling a few well-placed holes in it that I suppose would relieve some of the pressure around the restrictions..
anyway, does anyone else remember seeing or doing this? I have a spare exhaust for my NU50 and I'd like to try it out, and hopefully have it pushing 35mph in time for the sacto rally. either that or im gonna cut the header off and weld a pitbike exhaust onto it, one or the other.
