Hey. I'm the one who bought your Akrapovic full exhaust system a few months ago. I just recently went to install it and ran into a bit of a problem.... The header and collector pipe are correct. As is all the hardware... But the muffler is a slip on system and does not work with the full system because there is slight differences on the mounting part of the pipe.. First of all the slip on only uses one spring and a clamp. And the full system muffler uses 2 springs and no clamp... The one you sold me has a clamp and only a hook for one spring. Did my research and it's incorrect and contacts the swing arm when trying to mount it... Is this something you can explain to me?
