If anything there should be a bit more power due to the lower restriction in the end of the silencer. Exhaust flow both speed and volume is an interesting topic and goes hand in hand with intake flow. I think you're just fine without the killers. In fact maybe a teeny bit lean if it was set up with them installed. It depends entirely on the exhaust design but also cam design, air box air flow, filter, velocity stacks, port design. I've had bikes make power with baffles fitted, not lose any power with baffles removed or lose masses of power with baffles fitted. Even on 4 strokes you need an element of back pressure so a fully open pipe can have the opposit eeffect to what is intended and actually caue flat spots, holes in mid range or poor flow at high rpm. So in answer to your question it depends entirely on the bike and exhaust system and ther eis no cast iron rule, only a guide that says check everythign ona dyno and make a decision based on resutls only and not gossip.

A DB killer exhaust, also known as a decibel regulator, is a device designed to control the noise level of an exhaust system.
