I have the MIVV low mount CF slip on with CAI intact and am running the Arrow Low Boy tune. The bike runs and sounds great and there is none of that hesitation off the line or tons of popping on decel that others have reported.
As far as torque/power loss, don't really find myself thinking that at all. The bike is a beast and pulls like a freight train. Just my 2 cents..
