Hay Dave thanks for the "Nice Job"
Actually I'm using a TigerShark .91 not the SuperTiger, Sorry.
I wouldn't use a stock muffler due to having to cut the cowl all up. I got a pitts muffler for mine and will mount the engine side ways and the muffler will come out the bottom. Best I can remember I paid about $30.00 for my pitts. I don't know if the ST .90 stock muffler will fit inside the cowl or not now that I think of it, this thing has a big cowl.

Miloh.
