NOTE: all O 470 models require carb heat for the climb/cooling tests. The PMCF muffler was designed for performance as well as cabin heat. Carburetor heat models require a carb heat flange, CAHF, to generate carb heat. The PMCF muffler does not produce carb heat.

Notice

We cannot overemphasize to place your name on the production build list ASAP in order to provide you with a system when your name rolls the top. The most succinct term I can use for  the “Build List” is perpetual….or in a constant state of flux… changing by the week; so if you want one in the future you are urged to submit your contact and aircraft info ASAP!

With the 30,000 aircraft 180, 182 and 185 aircraft market being our largest market to date, the sooner your name appears on the list the sooner you will receive your Leading Edge Exhaust System Power Monster Cross Flow high performance FAA/PMA, US Patented dual exhaust system. If your name is not on the list you might never be able to get one….the choice is yours!

NOTE: When placing order please provide: name, address, email address, aircraft model, aircraft serial number and engine model. We will request STC permission statement information when order is assembled and ready to ship.
