Thanks for the responses.
while doing more research I found the following:

The author writes that he had the same problems with the right pipe (that's the one I started with) and that he had to saw 1" off to make it fit, I guess I will have to do the same...
From everything I read, it also seems that there should have been a clamp - which obviously didn't get shipped
last not least another question: it seems that the pipes are very close to the CV boots. Did you wrap your pipes with exhaust tape - or do you have any problems with melting CV boots?
Thanks again
