hi ben, tim de-catted his silencer and did a write up with pictures in http://www.xt660.com/showthread.php?...ight=stainless worth a look if only to give you a lay out of the internals

have you considered a single can? the type i used can be easily picked up on ebay. http://cgi.ebay.co.uk/Lazer-Produro-...item35af196691 my write up is near the bottom on http://www.xt660.com/showthread.php?...ighlight=paddy might be worth a look as the original unit is so heavy
