Okay..here is a serious answer. The header outlets are not even. Your shortie pipes are mounted directly to the headers so they arent even and probably wont be even unless you make an adapter or sleeve. I had shortie Hedman hot tips mounted on my 07 and they were slightly uneven also. On the stock exhaust the right side mid pipe is differently shaped from the left side mid pipe and the different shapes allow for the header offset and both stock mufflers hang evenly. Hope this explains it for you.
