Sadly i've not got much information to give about this system. It was going to be part of a track bike set up but I've decided to sell the bike after not managing to move the project on for 4 years. I looks to me that the older looking sections are original and clearly there is a new section that has been made up. It needs one more pipe section making up but all the tricky bits are there.

I've no idea but a quick Google says performance exhaust systems are made of steel, stainless steel, titanium and nickel alloys. The new section I would say is stainless steel. The rear box might be Titanium but the rest of it I've no idea. I weighed the rear box as it might give an indication and it's just over 3kg.
