Hello, I have just purchased an Akrapovic Evolution 4-1 for my Busa. On fitting the header into the collars it seems there are 2 small holes in each collar which the springs locate into. However, the headers on my system appear to have just one ring welded to each downpipe..this has got me a tad confused, I would have thought there would have been 2 rings to each downpipe. If any of you Gurus could give me any pointers or advice on fitting the header and their springs I would be very greatful, a nice piccy would be ace, thanks very much Davy.
