well...
blah blah. i found the wurth more expensive but it worked better....Also the tighten untighten bit isnt on the instructions..Next...
I tried the screwfix stuff and rated the wurth best, thats why i recommended it.

Fair enough. Where can our man get the Wurth stuff if he's not 'trade'?

Ask your local garage
I got mine from the local volvo garage cost around eight quid.
get hold of the bolt head with a decent, six sided socket and long handle. give it some welly and it will either come loose (likely) or snap the head off (less likely). either way, you can now disassemble the exhaust 
much less likely, is that it will round the bolt head off, in which case you'll need a dremel.

Right I have taken enough stick over this.
I started with the dremel tonight and I shall continue tomorrow. I am just gonna cut it all off and then put a new bolt in.
Lord knows why the last person to assemble the exhaust didn't tighten it up enough.
Theres a new cat on the bike so it must have been worked on in the last couple of years.

Why ???? Because that clamp doesn't really matter.
There are lots and lots of bikes riding around with no silencer and just the cat with a stubby.
The head of the bolt has an oval on it and 2 special washers, so it fits in a recess and doesn't spin
A new normal bolt may not fit in the recess and may to be re-shaped and welded in place
You could do away with the BMW chrome cover clamp and just fit a normal exhaust clamp at worst case
Some questions:
Do you have a Y-Piece fitted?
If so, have you re-used the original clamps (from the headers to the Cat) for the Y-Piece?
If the Y-Piece came with new clamps (the better quality ones did), then the bolts from the original clamps are the same as those on the silencer clamp.
I have two sat on the shelf.
Update.
A friend lent me a nut cracker. It worked along with some dremmeling to just get the nut off. The rest of the bolt is ok and can be re used. I have copper eased it in preperation for refitting, I am now awaiting a new rubber mounting bush and then i shall refit with loctite copper silicone gasket at the join.
For future reference the BMW parts diagram is not like the exhaust clamp fitted to 2011 models.
Hopefully the rubber mounting will be here to orrow then I can put it all back together again and get rid of the rattling exhaust. And it was probably losing a little power due to the lack of a seal.
I am glad I didn't cut the bolt staright through because as has been said the bolt is welded in place to allow easy fitting of the nut.
This has given me a chance to really polish the exhaust. So far so good.

be careful with silicone
Make sure its nowhere near the lambda probe, i put a lambda probe in a toyota previa once,i didnt have the proper anti seize stuff,so i siliconed it, and the silicone got soo hot it contaminated the lambda probe and frecked it up.
Also there was some major feck up with
's a few years ago round here, and they put some strange shyte in the fuel which was fecking up cars all over the gaff, beware, make sure its lambda friendly.

Only one more post here about a nut & bolt and after that it goes to three pages and qualifies for a side step to the 1200 section.

you never know
It may even go into a "what oi"l thread.How many people can discuss getting out 1 bolt...??
