Hi All,

I had asked a similar question a few months ago and have not really received a conclusive answer (I know you are all smarter than me, so I am hoping one of you has the key :-0)

I want to remove the muffler from my OS91FS, I am not in the least concerned about any noise problem, but I obviously need to have a pressure line to the tank. I was considering fashioning an extension to the header and routing it to some semi-scale positions on the plane, and then just tapping in a valve to attache the pressure line. Given the shape of the muffler, I am convinced that the design helps to up the pressure to sufficiently pressure in the tank....am I reading this right?

On the topic, is the engine a lot louder with no muffler? I have not tried it, but I am not convinced it is going to be toomuch louder..

Thanks all for any input you can offer..\regards
