Distinguished by a large, roomy cabin and legendary Beech Quality, the Model 23 series Custom and Sundowner aircraft inspire impressive loyalty and overall satisfaction among their many fans.

If honest, however, most of those same fans will admit that the aircraft’s take-off and climb performance are not among the aircraft’s most endearing attributes.

That’s precisely where Power Flow Systems can help: Our market leading Tuned Exhaust System removes the “choke hold” the aircraft’s stock exhaust system has on your engine’s performance. In so doing, it effectively applies an additional 10 – 15 Horsepower directly to the propeller of your “Baby Beech”, right where it will do the most good.

Here’s what you can realistically expect from that extra horsepower:

  • An increase of 30 – 130 rpm in static thrust
  • A take-off roll that is 100’ to 300’ shorter
  • An improvement in the aircraft’s rate of climb by 100 – 150 fpm
  • Reduced Fuel Burn (.4 – 1.0 gph) at your current cruise speed
  • CHT’s that are 15O – 30O cooler across the board.
  • A Service Ceiling that is 2,000’ – 5,000’ feet higher, with a corresponding
    improvement in performance at higher density altitudes

    So, if you are well pleased with the creature comforts and rock-solid reliability of your Model 23, but would be even happier if it had just a little more “Oomph”, you will find our Tuned Exhaust to be a very cost-effective solution to your quest for higher performance.

    Our industry leading 60 day money back guarantee means that if for any reason the performance benefits listed above fail to materialize on your Beech, you can return the system to us within 60 days of its installation for a full refund of your purchase price.

    PLEASE NOTE: Based on experience, we know that on the O-360 powered Beech 23 series airframes, the originally installed carburetor is often set too lean. Since the Power Flow System works by burning fuel in the mixture that would normally be pumped overboard unburned, these aircraft sometimes require that the carb be rebuilt/enrichened to take full advantage of the performance benefits offered by our Tuned Exhaust.

    Click Here to obtain a copy of a very simple test procedure that you can use to determine whether or not the carb on your aircraft is set sufficiently rich. If the results of this test indicate that yours is one of the airframes with a lean running carburetor, we can also refer you to a highly regarded carburetor rebuilding facility that is experienced in resolving these issues.
