Replacement Bolts for cat exhaust on 1999 R1100S
So, My 1999 R1100S with 74k miles on it started having the clutch slip on it. Ok, I kinda expected to have to change the clutch on it about that time, so I embark on the epic journey of tearing the bike in half (mainframe removal and pretty much everything rear of the clutch. The main obstacle was that I had to remove the catalytic converter to get the mainframe off. I snapped one of the bolts off trying to muscle it off (all the bolts were heavily rusted). Since the others were pretty much the same way I just dremeled the heads off. I got the dremeled headed bolts off with the help of some vice grips and generous amounts of Liquid Wrench, but the bolt that originally broke I'm gonna have to try an extractor or retap it.
My question is this, oh wise garage gurus. I was planning on using Stainless steel bolts. Is this the way to go? What is the best bolt material for this high temp environment?
BTW, it wasn't the clutch that failed, it was the slave cylinder. When I took the slave cylinder out of the back of the gearbox, fluid gushed out. Inspection of the clutch showed that it had been contaminated. Gummy. Bummer, because it still had plenty of meat left on the friction plate.
I highly recommend to anyone with a hydraulic clutch R11XX to drill in a drain hole, I plan on doing that post haste. I have ordered the new slave cylinder and clutch bits from Beemerboneyard, and will be reassembling my R11S this weekend.

Use 304 SS and coat it with anti seize before installing.

Don't use stainless steel on stainless steel as the metal will fuse together. Just one of the things stainless steel does. The OEM or replacement bolts of similar grade is sufficient.
I never had this problem as I take the exhaust off every now and again during the year to polish it, then assemble with a lick of copperslip to make my life easy.
