Introducing an improved version of the standard Experimental Cabin Heat Muff.

Each canister is made from industrial grade .063 aluminum tubes with .125 6061 T-6 aluminum end caps laser cut, welded and then machined to exact tolerance for ease of installation and a vibration free fit. Internally, each canister is fitted with 10 aluminum rods surrounded by copper windings for superior heat transfer.

The standard model is 8 in. in length with 2 in. intake and exhaust tubes. The end caps are machined specifically for the diameter of your engine’s exhaust manifold. Currently, we support exhaust diameters of 2.0 in., 1.75 in. and 1.5 in.


The Restrictor

Most Heat Muffs on the market today come with restrictor holes pre-drilled in the canister body; a one size fits all concept. We have designed a removable restrictor which fits into the warm air (exit side) of the canister.

By progressively enlarging the holes you are able to modify the flow of air through the Heat Muff essentially fine tuning the heat vs. airflow requirements for the type of aircraft that you constructed.
