Hi, just wondering, will it hurt my engine if I remove my stock muffler packing and that mesh roll that goes in the muffler too on my 2006 KX250F? The packing is due for replacement anyway. But Will it make a bit more power, because of less restriction? I'm not bothered by having to adjust the carb if needed, I just want it to be louder!!! But a tiny bit more power would be a nice addition, not too fussed on that though.
