People rarely use Pitts type mufflers with Four strokes

SlimLine would be my first stop though it is a little early in the engine's life for them to have one ready.
Since this engine is intended for the Pattern market I rather doubt that there will be much demand for a Pitts version soon.

The Pitts I have used and have seen used on four strokes are normally chosen because the OE muffler wont stay assembled. The usual procedure is to block one pipe so that you have enough back pressure to pressurize the tank and hold the needle settings to pretty much where they were with the stock muffler. I have run them unblocked as well with no noticeable power loss or gain---it is just that the main needle is out so far that it now becomes a candidate for vibration changes.

Last line-----I use the stock mufflers modified as necessary to keep them together and with manifolds to allow their routing to be very similar to a Pitts --- i.e. right behind the engine.

This Thread is 10 years old, he probably doesn't need one anymore.
