I have 2.5 in mine, but would love the 3.0. Ryan from Rush told me that 3.0 is best for a bike with the cat still there, but it can be done with no cat. (Thanks Ryan, for getting back to me.) Just wondering if somebody has duals (I have V&H Power Duals), & Big Louies with 3.0, and if you had to retune, or what did you have to do? How are you making out with the 3.0? Since you've had 3.0, would you recommend them or go back to 2.5? Thanks. I have a 2011 Limited Ultra. Stage 1. Dyno Tuned.

 

I've got almost the exact setup. The exception is that I have the 2" baffles. I was told at the time that the bigger the baffle, the louder the sound. I wanted a big bark when I get on it, but also wanted it to blend into the background on longer rides. I'm very happy with what I've got but I'll be watching this thread.
