I have been asked to post some more pics of my 6 into 6... I am on the case!!
The system seems to be custom made. The headers and pipes back as far as the silencers are stainless steel. Cbxtacy is spot on... the headers are very neatly triangulated. The peg hanger brackets have been modified and you will notice that the rear pegs are mounted slightly higher. My good lady who is 5'5" says it is not that uncomfortable!!
The silencers themselves... ( not that they do much in the way of silencing!!!
) are high quality chrome with alloy cones on the ends and mounted on brackets that run parallel to the shocks, the upper ones on each side point skywards!!!
When I bought the bike, I was originally keen to replace them with a pattern 6 into 2.... ( I was offered Â£1000 or about $2000 US !!! ) but the bike attracts so much attention and admiration, I thought I may keep them
I cannot describe the sound......... it is as near to a Formula 1 car as I have ever heard. As mentioned in my post on the brake forum, they do push out a lot of exhaust gasses. If you stand behind the bike on tickover, be prepared to lose your outer clothing, hat, wig etc.. It ticks over without missing a beat...
As I said, I will post some pics.
