PA-12 Exhaust Update

I just received a call from a customer named Danny D. who has a PA-12 with a 160Hp engine. He said he recorded all of his performance numbers with the stock exhaust and there were big changes after he installed the Leading Edge Exhaust System. Take off performance has improved significantly. He said his rate of climb went from 750’/ minute to 1150’/minute. That’s a 53% increase! In straight and level flight he gained 300 rpm’s.

Doug Drum of Indian Valley Meats, 907-653-7511 recently installed our system on his180Hp PA-12See photo of his very good looking PA-12 on floats in the photo gallery. He used electronic instrumentation for the following recorded gains: @2400 RPM fuel consumption was 9.2GPH and with the LEES exhaust system it dropped to8.3GPH and @2300 RPM it was only 7.8GPH. You have to keep in mind that this  is with an O360-180HP engine. He saw a static RPM increase of 75RPM and a 250’/per minute  increase in his rate of climb. With the stock exhaust he could never reach redline with the throttle full bore and  with  LEES’ exhaust he is now getting 2800 RPMand is considering repitching the prop for even greater performance.

Please note; all of our sales are sold as customer specific sales. Due to popularitry and demand of LEES’ products we do not stock any of the products we manufacture. The down payment is required in order to procure materials required to build LEES’ exhaust systems. Therefore there are no refunds on down payments.

Notice: We brush the pipes to a satin finish. In the future add $200.00 to all Piper Exhaust Systems for polishing pipes to chrome looking finish. We will still polish the tailpipe like chrome but not the other 4 risers leading to the muffler. The tailpipe typically stays shiny because it exposed to much cooler air; pipes under cowling do not maintain a chrome look.
