Test fly it with the cowl you built, it looks good. You really should be able to hide the muffler inside what would have been the vent, or oil cooler or, well, I don't know what it was, but I stashed a OS .32 into mine without the muffler showing. I then promptly crashed it on maiden by yanking it into the air too soon (first kit, flew only a mini super sportster before, so I just ruined a plane with inexperience). Give your run more than 5 feet, and don't use an bumpy cow pasture for a runway, heh.

Great looking plane, throw some pics up when you get her covered.
