Cesna 205/206/207 Exhaust

What led to this design was LEES involvement with their FAA approved welding and non-destructive testing facility that was started in the 80’s. That was over 20 years ago and now LEES has one of the most modern fabrication shops in the world. The original shop repaired many hundreds of Cessna 206/207 exhaust collectors. The popular Cessna 206/207 series aircraft are used for Air Taxi, Flight Seeing, US Mail, valuable freight hauling to isolated villages and also includes very remote big game hunting and trophy class fishing. These are some of the high priority necessities required to build a successful flying business. All of these very important business income sources come with some very big profit consuming expenses like; extremely costly downtime delays; having to get exhaust system removed and subsequently repaired by an approved facility in a timely and cost effective manner and that’s not always possible.
Having done literally many thousands of repairs was the impetus that brought this new unique design to LEES attention and that is when the “Best Pipes and Warranty in the Business” trademark was born!! The trademark is a good explanation why 75% of the Air Taxi operators in Alaska use LEES’ pipes. LEES eliminated the internal back pressure turbulence by mandrel bending precision, 40% thicker, equal length, 321 stainless steel primary tubes that all exit in the same direction. The spent exhaust gases merge in the patented 3-1 collector and then funnel through the integral venturi that speeds things up. From there, they exit through the ball joint into the muffler and finally leave the scene by way of the tail pipe. This radically new design reduced back pressure by approximately 50% which lets the engine operate more efficiently like it was originally designed to do. By reducing and balancing the back pressure the engine produces better power with greater fuel efficiency. You can expect approximately 10 more horsepower utilizing LEES’ pipes. LEES has a Canadian distributor that claims they have a customer that had his own dyno test performed and pulled nearly 15 more Hp.
Having more power is great, but more important than that is having an exhaust system that has a higher TBO than the engine. Would you believe LEES pipes have held up through 3 engine TBO’s? It is not uncommon after having accumulated more than 5000 hours of operations to have the original LEES’ collectors rebuilt to like new condition for a fraction of the cost of a new set. Another very important and unique attribute is the 20 year or 2000 hour transferable warranty. The warranty is not only one of a kind but also has proved to be a valuable sales asset. If the aircraft is sold the remaining warranty can be transferred to a new owner. These are a few of the reasons influencing LEES’ opinion they do have the “Best Pipes and Warranty in the Business”. tm
LEES exhaust collectors are direct replacement parts for Cessna 205,206,207 and 210 series aircraft. The Approved Model List is in the table below for the Cessna 205-210 Series Exhaus The current single set price is $1950.00 with no core charge. See above for LEES’ multi-set or fleet discount.
