Well everyone , my full system has finally been identified as a Full Skorpion (early Akrapovic) top end power system , they made two for our bikes one for top end power and one for torque. These are Quite a rare system and have been told one of the lightest. All I need now is some period Skorpion stickers for the cans ( something I think is going be a tall order) This is a pic of my end can
Many thanks go to Frank Schiefelbein from Ducati 900 SL.Com who correctly identified my system , he has had one on his bike for 18 years. This is a pic of his system.
