How much lighter is it then the stock pipe? Is it a lot louder then an uncorked stock pipe? Did it bolt wright on?

I am dying to spend some money on my bike. :)

Its a good bit lighter than the stock pipe,and it is a little louder than the uncorked stock,but the performance gains are unbelivable.I got the whole system so it just doesnt bolt right on and u have to jet it too,i just had my local dealer do it and so far its good.

Thanks for the info. What did you pay? What did you do for the jetting. Did you get the blue system? :)
