What is the best way to make a pocket bike quiet.

Hi

I bought a new pocket bike and it is VERY loud as two strokes normally are. I am willing to sacrifice some performance from my bike to make it quieter. All I want is to make it as quiet as possible.
Is it possible to fit two mufflers to the bike?
What is the best pocket bike muffler?
Could you fit mufflers for bigger engines to make it more quieter?

I am also interested to hear any ideas for home made mufflers or ways to make it quieter.

Thanks.

Oh and how much of a difference would a normal pocket bike muffler make?
