Can't compare to someone with a long d/p since I dont know anyone around here that has one.
I will say that there is a significant increase in power with just the shorty DP, but there is more to be had from the rest of the exhaust. I started with a Stromung DP; noticed more boost with the addition of a Stromung 3" dual tip CB and a little more power still with the addition of the Stromung midpipe with high flow cat.
