999 Header Bolts,

I'd like to take the exhaust headers off , the upper cylinder is ok, nuts loose, the lower 3 are going to round off, is it best to cut them off? Or leave as is ( I've a buyer for the exhaust system and planned to fit the OEM exhaust back on so this is not essential, but I'd like to

 

Am I best leaving alone? Will potentially cutting the nut off reveal a wrecked stud?

 

Assuming I can get the nuts off, how difficult is it to remove the studs?

 

Is a Dremel the best sort of tool to try and cut the nuts off ?

 

So, cut one nut off successfully , another came out with a socket with better access ( removed battery assembly thing), sheared the 3rd, so after 18 years could have been a lot worse. Just one stud to extract

 

If course you know that I mean I've had the bike 18 years, first time those nuts have been touched

 

And it nearly worked ...

 

Unlike mine

 

Extraction of the broken ( sheared ) stud failed at first hurdle, because of the shape of the head, and the stud that broke, there's not enough clearance to get the stud extractor on the remnants, looks like it's drill time....
