Re: need a muffler?
Do you mean you want to run the bike without any muffler at all?
As SevenStar already stated you will lose a lot of midrange but should gain some power at the peak. It's probably possible to map to minimise the former and maximise the latter - _if_ you could find a dyno operator willing to put up with the noise :-)
Your neighbours will also likely band together to either burn your bike or have you killed...
