Scott,
I used the OEM muffler that came with the G38 that was given to me. Just welded a tube to the muffler at the outlet. I lso added smoke fitting to the muffler. Very quite and works well.
Cheers
I love the way you have installed your G38 in this plane! [sm=thumbup.gif][sm=thumbup.gif]
Good many years ago, I did similar with a G38 and the stock muffler in a Pepsi Chipmunk with the difference that I brazed a stub of a 5/8" brass pipe to it and a Briggs & Stratton lawnmower muffler on the end of it. I also tapped the top of the stock muffler for a smoke nipple.
It was a great setup. Very quiet - had this nice deep throaty sound and did rob very little power from the engine.
I used 50-50 baby oil and liquid parraffin for smoke fluid
