I don't know about Borla or the other systems mentioned here but I have
a "fitment" problem with my Millen exhaust system. I have the header and
muffler and the tailpipe definitely is misaligned where it exits the
bodywork. It is close enough to the frame that it bangs against it on 
rough roads or with high side loads in turns.
Others have mentioned the loosening the various attachments and fittings 
can facilitate alignment but I have been unsuccessful in that. 
In all other respects I'm very pleased with this aftermarket exhaust system.
