Thinking about this:

You will surely LOOSE horsepower!
That's all I shall say right now.

Why if you mounted a single one to the Jardines or a CES header it probably make more HP but a little less torque
 
Mind with only a 6 inch by 2 1/2 baffle it wil bellow.... Good for those that like it loud
 
The biggest reason I want to do it is my left side pipe is banged up from my crash, and I've yet to find a new one.
 
You might loose 5-10hp, but if it's worth it to you asthetically, I'd say go for it. It's not like the beast is running short on hp or torque to begin with I actually looked at those a couple years ago and thought they were pretty cool.
 
If I was going to put something like that on my bike I'd want it facing forward and firing real bullets. As an exhaust tip.....well, it's sure not for me, but whatever floats yer boat I guess.
