On a 06 660 am i better off on leaving the stock on on? I have dual Mussy now but its load. i have the q cores in them. Will i loose any performance?

I don't notice any difference in performance when I install the whisper cores. If anything I think I pick up a little more low end performance with them in.

I think the only difference is when you spend a lot of time running high in the rpm range to get that full exhaust flow.

No, I'm saying to stick with the Muzzy's and install a set of whisper cores.
The nice thing about the whisper cores is they're very easy to take in and out depending what type of riding you're doing.

I got mine from UTV Inc. right there in Phoenix, great guys to deal with. Looks like $759 on their site.
