Fitted one to my son's (Brucetopher1 on here), 660R. I ended up drilling the heads with a 6mm drill, then unscrewing the remaining threaded part using vice-grips once the head of the bolt is removed. You will need new bolts, hex head are fine as replacements. A BIG spanner removes the Lambda sensor, easiest to slacken it while the pipe is still on the bike - It will be tight. Fitting the new headers is a real fiddle, a ball ended Allen key makes life easier with the manifold nuts, the alignment of the headers is critical... and you will probably get a very slight leak at the sleeved joint, this seems normal and will disappear once the bike has run a few miles and the pipes have reached operating temperature.
You'll really notice the difference, and it sounds lovely with the MM pipes :-)

Thanks for the quick reply and useful info. Glad to hear I'm not the only one to have issues with that. I've also got the same problem someone else had in there being a bit of excess metal from welding on the inside of the link pipe where the lug for carbon heat protector is. This means I'm also going to have to file that out - at the moment its stopping the secondary front pipe from sliding into place.

As for the leak where those two pipes connect - did you use some silicon sealant? I plan to do that once they actually fit together... am wondering if that will make a difference (?)

I fitted them dry as the fit was pretty good. Expansion with the heat of the exhaust and carbon build up over a period of time seems to have stopped the very slight leak that was there when they were new.

Cheers.
