I have a os engines .21 with a mac tunepipe. My question is where is the ideal location for the pressure fitting on the pipe?

At the widest point of the pipe is the safest place. Just make sure its going into the pipe chamber and not into the mufler chamber as some muflers will go all the way forward to the widest part of the pipe.
