Big Guns, DMC, or FMF?

I was wondering which is better. Big Guns, DMC or FMF power core IV2 with Powerbomb head? Let me hear some opinions and see any pics of any of them.
Thanks

I am looking for something with good performance and not loud. To be a little more specific.
Thanks for the reply.

The Big Gun exhaust is a good top end exhaust, but with the race core, it might be too loud for you (I don't know about the quiet core).

well, drop all the first ones, a white bros e series is a sweet exasuet, more of a bottom end mid pipe, tunable caus of disks, quiet wit spark arrestor

Don't get a dmc if you want it to be quiet.
