LEES exhaust collectors are direct replacement parts for Cessna 205,206,207 and 210 series aircraft. Our FAA /PMA approved Cessna 205 through 210 series exhaust collectors utilize TIG welded construction. Each equal length (+/- 1.5″) mandrel bent primary tube is fabricated from 1-3/4″, 321 Stainless Steel with a wall thickness of .049″ and is 40% thicker than most OEM systems. They are designed to serve as expansion loops which allows them to expand and contract as each of their respective cylinder dictates without adversely affecting the other risers. Each collector now employs 2 slip joints to allow more flexibility of the risers. Current OEM systems use a very rigid design that usually results in premature cracking at the flanges and weld joints. 

The LEES collectors do not use beaded ends and clamps, one annoying source of exhaust leaks and they are never very easy to remove. The primary tubes are routed into our patented 3-1 collector tube sheet. This helps merge the exhaust gases through the patented venturi and out the male ball joint. The outlet end is 90% thicker than OEM resulting in a much longer life. Our collectors not only reduce back pressure and noise but they also eliminate the common transverse flow and resulting hot spots in the stock system. We have customers utilizing our systems with over 5000 hours in use on the same system and no downtime. Some of Alaska´s busiest Air Taxi Operators employ our exhaust collectors with very good results. They have very demanding schedules and operate in some of the harshest environments in the world. Product reliability was the number one priority according to our customer survey response cards. LEES collectors are direct replacements for OEM systems and require no additional modifications.

Request a quote or call us to check the current price of collectors. Reference the following part numbers (L/H) LEES1250256-3 and (R/H) LEES1250257-3. There is no core charge.  We do not recommend mixing our collectors with other brands due to the potential unbalance in exhaust back pressure.
