That is a great weapon, and the terrain looks magnificent. Your bike is a credit to you.
The silencer modification is interesting. About 30 years ago, there was a fad here to add a VW Beetle tail pipe as an extra silencer and, it was said, to improve torque slightly, with the extra length of the exhaust. I had one on my XR 250 - the best trail bike I ever had, but it did not sound like the Triumph with its Supertrapp - so you may begin a new trend. A Scorpion may fit, though, and save much weight.
