Just thought that I'd point out 2 things guys:
First, you are responding to a thread that is nearly 26 months old.
Secondly, that exhaust is not a "3 into 6", it is a 3 into 1 into 2 into 3, so unless its owner performed some alchemy to deal with power loss due to the strangling/convoluted nature of the OEM setup, the power loss will be even more pronounced with the setup as pictured.
I also prefer the looks of a more "balanced" exhaust setup with pipes on both sides of the bike instead of the more efficient and much bigger power-making 3 into 1 design, but, in this case, I don't think that you can have your cake and eat it too on a naturally aspirated R3.
BTW, ThingKing, Bulldog's exhaust components look bone stock down to the collector pipe, which is why I believe that it could only subtract HP & Tq from the motor's output, not add power. In other words, it's all show and no go!
