Can anyone help me here? How is this done, and will it hurt the performance of the bike at all?

It has 3 rivets in the end of each pipe, how do I remove them and then what do I do after that?

I am not much of a bike mechanic so any help I can get would be appreciated.

Also, sometimes I hear a popping sound from under the tank... Usually goes away after a few mintues, but what would cause this noise?

Thanks!!!
