Yes, I read all the posts about how the 08 is corked up and it needs a pipe to open it up. Well, I waited a couple of months and finally got a DRD stainless full system. First ride....holy sh*#! It looks like the same bike, but it acts like its on steriods. I've never experienced a power gain like this; I feel like I have to re-learn to ride this beast. All I can say is... unbelievable; if you haven't upgraded from your stocker yet, you're missing out.
