Minis are pretty quiet, so you don't really need a silencer. A longer barrel would send stuff farther though.

My minis sure arent quiet, the barrels are pretty long too, it seems to me that with different fuels i get quieter or louder shots, and Scope is right, that sure is a ghetto looking gun

depends on C:B ratio the less force being used to push the round the louder the bang. So try making a long barrel or use a smaller chamber if it is to louder.
