It's a Thunder Tiger .15 on a small P39 Airacobra Kit. Unfortunately, I installed the fire-wall backwards, so the engine mount was reversed. This forced me to flip the engine in order to align the engine correctly. So instead of the muffler being below the plane, it is actually pointing out of the top.

I'd like to direct the exhaust under the wing to avoid the mess.
