Hi Paul and welcome.

I've moved your thread from the "Reviews" to the more appropriate "Exhausts" section - you'll get a better response from members with it in the correct place.

As for the exhaust swap, an XT600 system won't fit the 660s. There are only two options for a 2-1 system for the XTR/X (plus the option of going to custom fabricator). They are...

OTR - http://www.off-the-road.de/en/XT-660...-e-marked.html

Metal Mule - http://www.metalmule.com/luggage-sys...exhaust-system

Why not pop along to the Newbies Reception Lounge and introduce yourself to the rest of crew...
