Hi, I think most owners have had ths problem to some degree, some like me get lucky when taking the old bolts out. I replaced all the bolts with stainless and lube them a couple of times a year.The exup is a great idea if only all the bolts and various parts were stainless steel but Yamaha decided mild steel would be sufficient.
Extracting the old bolts shouldn't be too much of a problem but the broken tap is more of a challenge, if the valve is not damaged beyond repair you could get the tap spark eroded at an engineering shop. From experience trying to drill it out is just a waste of drill bits.
You could look for one second hand on eBay but they are very rare on their own, a better bet is to look for an exhaust complete with valve from either a Fazer or R1 '98-'01. You might find one for under £100 if your lucky.
Best of luck.
