No such problems with mine when I had it, although it looks like they have redesigned the "Y" section to include some springs, I assume to make better fitment, but I wonder what else was changed that isn't so obvious.
However, looking at my version of the exhaust, there is/was plenty of grip from the clamps to hold on the tail pipes, so you should be able to pull them both out a few mm so they are level and straight.
