no silencer

I've heard one on you tube , It sounded loud and very Crappy , Loosing power for sound Is Ricer If you ask Me ! , Take your silencer and Pack it with #0000 Steel Wool ! , I did with my Dmc alien and It sounds great to me !
 
I question the idea that power is lost when the silencer is removed.

I found that in removing the stock silencer there seemed to be a slight increase in power, or was the noise fooling me into thinking that.

Removing an after market straight through silencer should have no affect on power output.
