I've read some posts on this issue. The answer is Yes!

A diesel requires no back pressure. So the bigger diameter and shorter the run, the better.

There have been a number of posts on this issue. I'd do a search if your interested and especially look for a post by Ted Jannetty, of Jannety Racing. He tested this issue and with the larger exhaust it doesn't pay performance dividends until you get around 500hp, I believe. On the new trucks defueling starts and performance drops off. Check it out.
