As to the studs breaking mine were in a right state, the top clamps had rotted away, the studs were thinner than they should have been and the nuts were no longer recognisable as nuts, I had to cut the exhaust off, and all my studs came off by unscrewing, I had a few tense moments, I did apply some heat to the stud and I used a stud extractor, when I replaced the studs I got mine from a local Vauxhall dealer as they were cheaper than Yamaha and I bought dome head stainless nuts, no more hassle getting those off in the future.
