Does anybody recognise this exhaust system? It came with a 750M motor I picked up and both were once attached to a French 750 "Teapot" (GSX750F). It says "Nikko" on it but it looks a bit like an old Piper or Alfa four into one except this one is a four into two into one system. It looks like it has a baffle in the end and it's a complete system rather than needing a link pipe and a can, i could be wrong though? Anyway it needs a bit of weld to a crack around the collector but it it's a decent pipe I'm going to put on my 600F/GSXR750 project! :-)
