I have the same set up, I was thinking of getting the CFR's. Make sure you post your results.
Sorry but I can't hold this in any longer....I tune a lot of bikes with a lot of different exhaust systems. Some systems better than others, BUT the 4 or 5 bikes I tuned with the CFR systems are by far the worse performing pipes I have ever seen except for the Paul Yaffee's short 2 into 1 that dumps out just forward the saddle bag.
Not only do you loose power on the bottom end the torque falls off quickly killing the top end also and no mater what the build, 103'', 110'', or 120r's the graphs all look the same.....terrible. I know they sound good and they even look good but they do not perform well at all. The bikes run ok but they are no where near running great. I believe you will be seeing alot of these systems on Ebay soon....lol..!
I realize I might be tramping on a few toes here and I'm sorry for that I don't want to cause a war here or bad feelings but I just can't go on seeing post that say how good their bikes run with the CFR systems when the CFR's leave tons of power on the table.
