Is is possible to cut off the end of the stock pipe and partially gut it to remove some of the baffles and weld it back on?

Or just straight pipe?  Would that actually hurt performance?

yes,yes and yes and it sounds like crap and people with think your bike is a piece of crap.
Do it the proper way or not at all or you will get chewed up and spat out by a stock unmodified GS's

Yup, I had the pipe off of mine for a couple of days and it sounded like crap and may have been a little slower.

If you're really cheap, you can drill a hole in the end of the can below the outlet. Start small and go larger as you think you "need to"

A better idea is to get a stock exhaust off of a dirtbike or larger sportbike, and put that on. People thow them away after they get expensive titanium cans.

Pull the exhaust, send it to me, and I'll make it a straight through baffless system packed with stainless steel and glass.  It'll look stock but you'll get more sound and, with propper jetting, you'll gain a horsie or two.

I drilled holes in the end.  Sounds fine to me.  No worse then some other rice rockets I have heard.  I was just trying to find another way to get more flow.  I messed up and put 155 jets in it.  Runs great below 50 deg f.  can hit 120 on speedo no problem.
