Questions about x6m exhaust

[tonymac1]

Hi everyone, I'm planning to get a new exhaust system for my x6m, but it's hard to make a decision between eissenman, akrapovic and meisterschaft. I watched some videos but it's hard to tell the differences. Does anyone have any suggestions for choosing among those exhausts? Or some other brands? I would be more than pleased to listen.

Also, does anyone know the exact prices for those exhausts?
Please help me everyone
