CustomPC,

Thanks for the lookup, I'm new to the forum scene. I did mean your install. It looks very intersting and your post regarding the Bisson Pitts style muffler is on target with what I had heard.

Great looking plane and thanks for the help. I have a 55AX and a slimeline Pitts muffler and a 46AX on my son's trainer. Both excellent engines. I'm sold on the AX series up to this point.

Any experience with a Slim-line on the 75AX? Does it have similar results as the Bisson?

Thanks,
