After overcoming several daunting challenges, including supply-chain SNAFUs, a global pandemic, and a couple of hurricanes, Power Flow is steadily increasing the production rate of its new Power Monster Cross-Flow (PMCF) exhaust systems for a variety of Cessna aircraft powered by Continental engines.
In 2019 Power Flow acquired the STCs, tooling, and production machinery for the PMCF systems from the estate of the late Dane Wagner, president and chief designer of Leading Edge Exhaust Systems in Anchorage, Alaska.
“Using Mr. Wagner’s ground-breaking designs as a starting point, we have made significant improvements to both the product itself and the quality control procedures,” said Darren Tilman, president.
The exhaust systems are designed for Cessna 180s, 182s, and 185s powered by Continental O- and I/O- 470, 520, and 550 engines.
The company reports it has shipped nearly 65 of the systems to customers around the world.
Officials also report they are expanding the size of the production facility, as well as the number of employees, to meet customer demand.
Power Flow tuned exhaust systems are FAA approved via STC and provide an increase of 30 to 130 rpm, an additional 100-250 feet per minute in climb, and the ability to go the same airspeed while saving up to 2.2 gallons per hour in fuel burn, according to Power Flow officials.

Je suis intéressé pour mon Cessna 185 année 1979 CGNOA
“No replacement for displacement.” Horsepower increase claims with these exhausts is wild surmise, never seen a bit of difference, it’s all marketing. I bought a hotrod exhaust for my supercub with big claims, it’s was louder but no better, lotta marketing there too, everyone went back to stock.
I have been waiting forever for a system for my Hawk XP. Alas there appear to be no plans since this was a low volume aircraft. Isham has an STC for a bit more power but they get it through increased RPM’s and prop governor neither of which I favor. What
would be best would be the original 220hp that the I0360KB6B was designed for in the
T41 military version of my aircraft!! Oh well.
Brad Isham’s performance enhancers amounted more noise, and the decision that Cessna didn’t want to eat into the performance of the 182 market. As for the T41 one had a fixed pitch prop (Air Force) and the other a constant speed for the Army.
I flew a T41-C that the USAF Beale Aero club had, N7751L . The 210 HP and fixed pitch yielded a great 1,500 fpm roc, but cruise was 128 mph at the 2,800 redline.
The T-41-D had the constant speed prop.
What about us O-300 drivers?
We could certainly benefit from a little extra!
In Canada the operators hop the engine used on the float planes with C-85 pistons which will bump the compression ratio up some as well.
Is there any hope for ever seeing a system for the Continental powered C150/152? These little guys would benefit tremendously from a little “extra juice”!
They need the new TCM O-200D piston of 8.5 to 1 compression. They love 100LL w/out the plug fowling problem.
