Has anyone removed the Akro dB killer?

Not an engineer here,

So that means chamber ON or OFF gives more power? anyone tryed it?

Sorry for all the questiones, but I think everyone is acustom to free flowing exhaust means better performance, but I know this small bikes kind of like the back pressure. So just the dyno can say what is best.

Mine was a b..#$!@ to get out. Drilled the bolt out and no way did this thing want to move. Ended up hammering it out with a big socket and long extension through the inlet side of the pipe. Took about 40 good hits
