Dumb ? here Why do Moto GP exhaust have two outlets. Im interseted in buying one for the cbr1000 for performance and sound. Any comments or answers.. PLZ help

 

I have the Arrow moto GP exhaust on my 06 1000. Love it! The sound the pergormance and above all it handles much better dumping that stock exhaust. The only thing is you will have to modify your right side lower fairing. This has to be done because Arrow headers are straight unlike the stock headers. If you look at cylinder 4 pipe it has an extra bend to go around the fairing. The Arrow pipe sits right up against it so what I did is use a Dremel and cut away some of the fairing. Nobody can tell that I cut it, I had to tell them. I'm totally against any fairing modification but this looks good. Deffinetly worth it.
