tuned pipes
I'm going to put a tuned pipe on my O.S. .46. It's a mac pipe. I've been researching the tuning process and found good information on how it's done. My question is this: Is the end of the pipe opposite the header supposed to be supported some how to the body of the airplane or is it just left free. It seems to me that only being supported by the silicone piece between it and the header would allow it to flop around. That doesn't sound like such a good idea. Any suggestions?
