I have a 1200 with the large 8v exhaust looks like an 8 from the rear. The bike came with a Termignoni which I want to fit but the clamp tube is cracking up. Is the standard Termi stainless or plated? I will have to cut off the 60mm clamp and weld on a piece of tube. I did try welding up the cracks but it is thin and my welding is a bit pants. Also the pipe is stained and if the welding works I will need to polish out the mark it’s about 150mm long and all round the pipe(corrosive liquid spill maybe). So are they stainless?
