After months of waiting, I finally received my Sil Motor carbon fiber exhausts this week. They are beautiful, but unfortunately, the inner diameter of the pipe end of the muffler is 41 millimeters and the ID of my ST2 stock muffler is 45 millimeters. The Sil mufflers don't fit on the link pipe.
I emailed Carlo Carpi and he responded with this:
"I called Sil Motor and they got the answer: ST2 has 41 mm diameter link pipe, and what you received it is the right one. You will probably have a ST4 exhaust which is 45 mm."
Is this correct? I am unaware of any changes to the exhaust system on my ST2, and it still has the original cans. What is the real OD of an ST2 link pipe?
