Look under the CONSTRUCTION link for the Mousse Can Muffler building instructions.

Use a can that measures exactly 1.75" diameter. The length of the can be anywhere between 6.5" and 7.5 but the 1.75" diameter is critical.

Adjust the header length so the distance from the rear of the header mounting flange to the can measures 4.5" to 4.75" with only about 1/8" of the tubing sticking inside the can.

The exhaust tubing should be 5/16" ID. The length doesn't matter. In fact, I don't even bother with the exhaust stingers anymore. Just open up the nozzle end of the can to 1/4" and start from there. Make sure you remove all of the nozzle parts (rubber washers, springs, and plastic pieces)

For the TT 42 w/MCP a Master Airscrew 11x4 works great.
