Ineed one that will quiet this monster down. Iran mine up for the first time and it is much louder than expected.

It will eventually be going into a TF GE Mustang, so what ever I get will need to fit inside the cowl. Right now it is mounted upright in my Dewey, but will be inverted in the Stang.

Jtec has several different mufflers for this engine

There is an aluminium stack insert for the stock muffler which is available from most DLE dealers that tones down the engine's exhaust bark quite a bit and only marginally affect the engine's performance.

Go with the Jtec radiowave inverted wraparound. I have three or four of them and they are very quiet. Expensive but highest quality muffler on the market. The stock DLE muffler is a JOKE! Its about as thick as two sheets of aluminum foil.
