I have a Super Tiger G90 with a pitts-style muffler to go in the P-51. If I invert the engine, the two pipes from the muffler stick out the left side of the cowl. If I side mount the engine with the pitts pipes going down . the engine head sticks out about a half inch.

The engine runs fine inverted, but which would look better protruding from the cowl, the 2 pipes, or the engine head. Thanks for your opinions.
