Did you sell your Drago's? I'm sure you're aware he offers a performance guarantee, but you have to show both dyno graphs and they have to be done within a week of each other I believe.
Did you do anything else other than just the pipe swap, or any other variables? (ie- Drago ran a canned map, D&D had a custom tune?).
Is your D&D a lot louder?
I bought his Dragula pipe. I'm a Propipe (last 3 bikes) guy, but decided to try something different. For 06Ultra the pipe was a little too quiet, but for me it probably won't be quiet enough. I'm just a die hard 2-1 guy, first and foremost. I like the looks and performance of a 2-1 pipe and the Dragula from what I've reading has performed very well, it looks great, and apparently good quality. I'll have Dyno Bob tune the bike and see what I get.
I may drop in a cam, but I will probably leave for now stock until I get some miles on it (I just had my 1k service) and I just don't know much about the 110 reliability, and if takes a dump, I want it to be on Moco's dime.
