American Legend Aircraft Company 0-200

Aircraft Exhaust Corp. is the original exhaust manufacturer for over a dozen LSA & Experimental aircraft companies.

From the American Legend Aircraft company with a Continental O-200 engine (LSA), to the Murphy Moose aircraft with an M-14P radial engine (experimental).

Lancair 0-550 performance exhaust
Within the last 15 years we have owned and operated five different repair and manufacturing companies specializing in certified aircraft exhaust for piston powered aircraft.

We have now moved into the LSA & Experimental aircraft.

We have been the leader in new innovations from; ball joints that allow expansion and contraction from hot to cold cycles in a 360 degree area, the dual 3 into 1 and 4 into 1 collector system with equal length headers to get maximum HP out of your engine, our Rotax 912 series exhaust that uses backup rings with captivated springs to eliminate the big springs on Rotax that break and are lost in flight. The Rotax .060” wall mandrel, bend directly out of the cylinders and up or down  for maximum clearance from the propeller to exhaust keeping the cowling very tight to the engine, and our 4 into 1, 1 ¼ “Rotax mandrel bend collector helps get maximum power from the 912 Rotax engines. We have built tooling to form our own sockets to the engines and flanges that hold the exhaust in place.

We use 321 stainless steel when ever possible. 321ss is capable of operating at a higher temperature than 304 ss, and has a much longer life in cycles of hot and cold.

How it Works

Aircraft Exhaust Corp. is the original exhaust manufacturer for over a dozen LSA & Experimental aircraft companies.

After a manufacturer has determined that we are the best solution to their exhaust needs we then find out their exact requirements – airframe, engine, performance, Db requirement, other. Then we send out a PVC mock up kit with mock up flanges that are sized for the proper PVC determined by engine manufacture and with either a mock up collector, muffler type or single side stacks.

4 into 1’s (4 cyl) and dual 3 into 1’s (6 cyl) don’t require a muffler in the system, this is due to the long length of primaries from the exhaust flange to the start of the collector (typical 28” -36”) this long run of primaries along with the collector and tailpipe provide a muffling effect on the exhaust pulses. Some overseas customers will require additional Db reduction which can be provided by adding an additional muffler just past the collector. The HP increase due to the collector style exhaust will be reduced slightly with a muffler but Db reduction will be what is needed for overseas operators. With a collector style system the cabin heat is pulled off a straight primary section which provides high temperatures for good cabin heat. Since the primary is made from 321ss the high temps will not hurt the tubing under the muff. In aircraft that are known to operate in cold conditions we can also add heat pins to help pull heat from the primary to get even more heat for cold climates.

A Carb heat muff can also be ordered for carburetor engines, it also mounts on a primary tube but only requires 5″-6″ of straight. The carb heat has a series of holes which draw air from the engine compartment into the muff, as it is pulled past the primary it is heated and is sucked into the carb creating carb heat of 95+ degrees over ambient -(FAA requirement for temp rise for carb heat on certified aircraft). Both the cabin and carb heat shrouds are typically 3″ OD with a port in and a port out. Typical scat size for good air flow is 2″.

Production Run
AEI builds the cabin and carb heat shrouds from stainless steel to assure that their will be no failures due to the extreme heat from the primary in which it is wrapped around.
