Ready for MORE of what you got your Husky for? In close cooperation with McCreery Aviation of McAllen, TX, (a well known and well respected Aviat Dealer), Power Flow Systems, Inc. has developed a new Tuned Exhaust System for the Aviat Husky. This exhaust system is FAA approved by STC (Supplemental Type Certificate) for all A1, A1A, A1B and A1C-180 models powered by Lycoming O-360 engines.
In recognition of the superior performance offered by our system, Aviat Aircraft now offers our Tuned Exhaust System as a factory option on all new production Huskies with the Lycoming O-360 engine.
Current Husky flying customers have confirmed our system’s performance improvements:
Shortened take-off roll (by as much as 367 feet)
Improved Climb performance (8% - 15% depending on altitude)
Increased Service Ceiling (by 2,000 – 5,000 feet)
Faster Cruise Speed (+ 5 mph) for a slightly higher (+.5 gph) fuel burn,
Reduced Fuel Burn (.4 – 1.0 gph) at your current cruise speed
Vastly improved (by more than 100º F!) Cabin Heat Output
Don't just take our word for it - listen to what just some of our happy Power Flow customers have to say about the Power Flow tuned exhaust system on their aircraft:
So whether you like to use your “Dawg” for exploring some of those awe-inspiring back-country air strips, or just touring the country from a lofty (but not too lofty) perspective, Power Flow’s innovative Tuned Exhaust System will give you more of the breathtaking performance for which the Husky is so well-known.
As a matter of fact, several of our customers have observed that our system puts the performance of their 180HP Huskies squarely on a par with Aviat’s new 200HP versions – at a very small fraction of the price differential between those two aircraft.
And, of course, our industry leading 60 day money back guarantee means that if for some reason the performance benefits listed above fail to materialize on your Husky, you can return the system to us within 60 days of its installation for a full refund of your purchase price. Fine Print? You just read it.
As noted above, the cabin heat output of Power Flow equipped Huskies is over 100ºF hotter than the stock cabin heat, so existing aircraft need to install Aviat's optional metal heater vents or watch in rapt fascination as your plastic vents are reduced to molten puddles before your very eyes (Trust us – we’ve done it!).
Husky aircraft not equipped with Aviat’s optional Vernier Mixture control should upgrade to the Vernier Mixture control. The Vernier control operates like the propeller pitch control for precise adjustment of the mixture. This allows you to take full advantage of the improvements in performance and fuel economy made possible by the Power Flow System.
We also strongly recommend the installation of the Challenger Air Filter system to further improve the performance of your Husky. Utilizing K&N’s high performance, reusable filtration media, the Challenger offers a very cost-effective improvement to the induction side of the engine. It is a great complement to the improvement in the exhaust side of the engine provided by Power Flow.
As a convenience, you can order the heater vents, mixture control and Challenger Air Filter package from us when you order your new Power Flow Tuned Exhaust to make installation easier and save on shipping costs.

A couple of other important pieces of information:
#1.) We strongly recommend that the aircraft's propeller be dynamically balanced to within 0.2 ips (inches per second) upon installation of the Power Flow System and every two to four years thereafter. If the propeller is dynamically balanced within 25 flight hours of the installation of the Power Flow System and you furnish PFS with copies of the logbook entries confirming this, PFS will extend the warranty on the Tuned Exhaust System from 12 months to 24 months or 500 Flight Hours (whichever occurs first).
Doing so every 2 - 4 years thereafter will dramatically improve the useful life and the reliability of every component that is bolted to the engine, including the Power Flow System.
#2) The Power Flow System has no service life limit. It is designed and built to last several thousand flight hours and will quite likely be the last exhaust system you need to buy for your Husky. As with any high performance system however, it must be maintained properly. Every 500 flight hours or annually (whichever comes first) the four slip joints on the system must be cleaned and lubricated with high temperature anti-seize compound.
Most customers have this maintenance performed during the aircraft's annual inspection which adds about 2 hours of labor to the inspection. We have had several of our Tuned Exhaust Systems rack up over 4,000 flight hours of trouble free performance (7,000+ flight hours is the current record in a commercial operation) as long as this maintenance is performed as required.

Customer Reviews on the Power Flow Husky Tuned Exhaust System:
McCreery reviews the Power Flow System for the 180HP Husky
"I had the opportunity to go to Florida and test fly the Power Flow system for the Husky and wanted to share my seat-of-the-pants, barely scientific observations with you. I’ll leave it to the Power Flow guys to give you the data
The day I got to Daytona was a little uncharacteristic of Florida weather- although the temperatures were nominal the winds were about 10 gusting to 20 out of the south, right down the departure runway. This presented some difficulties in measuring takeoff distance but once in-flight, didn’t much affect the aircraft.
They are using McCreery’s 2008 A-1C-180 with an 80” Hartzell prop and 8.50 tires.
With full fuel and me at 240 lb, the airplane was off the ground before I rolled through the numbers, no doubt helped by the breeze on the nose but there was definitely an increase in power and acceleration from the Power Flow system. Fuel flow on takeoff as shown on the VM1000 was higher than I’d ever seen with a stock Husky before (17+ gph), also indicating more power being created.
Climb-out was somewhat limited by a 2500’ ceiling over the mainland, but while climbing over the runway, again I could tell there was more power than the stock Husky at work.
My SOP experience reminded me of the climb performance of an early (light) A-1 as compared to the A-1C. I did not have a “200HP” experience I had hoped for but there was definitely more kick with takeoff and climb power applied.
EGT spreads were equivalent to what I was used to seeing, although I believe that peak EGT was higher due to better exhaust gas scavenging. I’ve been using TomD’s “full throttle less ½” for so long it’s automatic and the CHT’s were about the same as non-Power Flow for the climb-out.
Once off-shore where the clouds finally opened up, I did a “time-to-climb” from 12,000 to 14,000 feet that gave me a baseline for comparison to another 2008 A-1C-180 that I have here in McAllen, TX. The PF airplane beat the stock airplane by 1 minute in the climb with very similar OAT’s. The differences between the airplanes were that the stock airplane had an MT and 26” tires and the PF airplane has 8.50’s and the aforementioned 80” Hartzell.
When the climb test was over, it was time to go back to DAB against those same headwinds. Once leveled out at 2200’, I found the PF airplane at 75% power demanded about 1 gph more than the stock Husky system for 75 degrees rich of peak as I normally run. There was definitely more speed but I’ll let Jim describe the measured differences. Indicated airspeed was in the yellow arc.
Finally, there was the increase in heater output temperature that so many have lusted after. I had the opportunity to take a new Husky from Afton to northern Maine a couple of weeks ago and spent a lot of time at altitudes where the OAT was 0-10F. I now better understand why you cold-weather Husky owners wish for more heat! "
