The end caps are ali, held on with rivets, so it was a simple job to remove them.
The carbon fibre is a cylinder that slides off, so I reversed it in order that the strap (stainless, came with the can) in its new position would cover up the the same part as before, avoiding too many scuffs showing.
As my connecting pipe is 2" o/d, and the R1 has a 60mm o/d inlet pipe, Andy W made me up a short stainless inlet pipe to fit on the cutoff original inlet pipe, swaged to fit. Hampshe kindly tig welded it on, then I put the ali end cap back on.
At the other end, the end cap had a stubby little overpipe, but I wanted somethiong to direct the exhaust away from the rear wing a bit. Angle grinder to the rescue and I made a new tail pipe from the original inlet pipe that I had cut off. Luckily it had a built-in angle so I could fit it to angle out and down. As it is cosmetic, I just cut and bent some tabs from the original ali overpipe and riveted the new tailpipe on.
My original silencer had an ali strap fixed to a rubber mount which was itself fixed onto a bracket of angle steel bolted under the floor. Because the new can is slightly wider diameter and the new strap's bolt holes are further out, the old mount didn't work, so it came off. I used a piece of 3mm ali angle to make a small bracket, fixed it to the underneath of an angled rail inside the cockpit (slid through a slit in the foam to lie flush with the outer skin), then drilled through the bracket and the skin. The original rubber mount (Land Rover engine mount, so it should be strong enough!) is bolted onto the outside, and the strap fixed to it. I think it looks quite neat, and in fact it preserves the original bike application by having the can hanging down from an upper mounting point. This should also reduce stress on the strap, which was a bit of a worry when I tried it on the original mount.
