I don't have anything on paper to back up my choice for the 4" w/ muffler, but I did my research a few months back and I found that most people found the drone of a straight pipe annoying, and a 4" will leave more than enough room for hp gains in the future.

Good luck! I'm more than happy with my exhaust setup.
