Selling my Trinity - Need a S.A. Replacement

I say there about the same. You don't get any real power advantage from silencers. There mainly to control sound.

FYI: Pipes work around an amount of back pressure.The silencer controls a good amount of that back pressure. Although you may think there just for sound this is not the case.Take your silencer off and see how slow it may get.

But would you feel any power difference between silencers?
