To the first lucky person if you take your CT into them for first fitting
I think it'll look great on the CT
I've had one of these on a few bikes in the past, they're well made with removable baffles, road legal, with a nice not to loud note with the baffles in and loud when removed in polished or brushed finish stainless steel. http://www.campbellcustom.co.uk/
I contacted John Campbell to see if they did one for the CT, he said no but he could offer me a 50% if I took my bike in for a fitting as they are looking for a CT to make a jig.
Unfortunately I'm over 200 miles from him so its not practical but if anyone is interested email him on email@example.com for the same deal.
