Cessna 177 w/ O-320
Bolt-On Horsepower. Perhaps no other single in Cessna’s line-up of iconic aircraft inspires as much fanaticism among its Owners and Pilots as the Sleek and Stylish Cardinal RG. Our well-proven Tuned Exhaust System (now installed on nearly 20% of the entire U.S. Fleet!), gives your bird the performance to match its exciting looks!
- Make your Cardinal a faster, higher flying bird. Similar technology has been used in race cars and motorcycles for years, now it is available for your Cardinal RG. By more effectively emptying the cylinders of spent exhaust gases, our Tuned Exhaust
System immediately gives your RG the following improvements:
- 5 -7 knots faster cruise speeds
- 10% – 15% increase in rate of climb
- 0.5 – 1.5 gph reduction in fuel burn at equivalent airspeed
- Improved Take-Off Performance (100’ – 300’ reduction in ground roll)
- Increase in Service Ceiling of 2,000’ – 5,000’
- Cooler CHT’s
Don't just take our word for it - listen to what just some of our happy C177RG customers have to say about the Power Flow tuned exhaust system on their Cardinal:
You can also click on the Reviews tab near the top of this page and see other reviews and view more videos.
The Power Flow is a versatile, quality constructed, complete replacement of your entire exhaust system. The entire system is constructed of 321 grade stainless steel and includes minimal structural welds in the cabin heat section for improved safety.
All necessary parts are included for easy installation on your Cardinal. Our customers report an average install time of between four and seven hours. The system can be installed by one of our dealers, by your local A&P, or you can fly your plane to us for a local installation. Fly in with a standard Cessna 177RG Cardinal, fly out (usually the same day) tuned for performance.
Our industry leading 60 day money back guarantee means that if for some reason the performance benefits listed above fail to materialize on your RG, 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.
Price for C177RG with Lycoming I/O-360 or I/O-390 Engine:
$5,750.00 with Polished Tailpipe / $5,950.00 with Ceramic Coated Tailpipe.
Polished or Ceramic?
The Ceramic Coated tailpipe is a cosmetic enhancement that hides the heat induced discoloration that is characteristic of stainless steel (think of the "bluing" you see on the muffler of a motorcycle).
This discoloration has absolutely no effect on performance or reliability but the ceramic coating covers it up permanently. Otherwise, the polished tailpipe begins to discolor after a few hours of flying time.
It can be re-polished anytime, but if you are proud of your RG’s appearance and would rather spend your time flying than polishing, the ceramic is a nice feature to have.
Challenger Air Filter:
The Challenger air filter replaces the disposable foam filter media found on most aircraft with K&N's high efficiency reusable filter media which provides up to three times more air flow to the intake manifold of the engine. Our own flight testing has repeatedly confirmed Challenger's published data:
#1.) A definite boost in manifold pressure (up to ½ inch);
#2.) An increase of 1 - 2 knots in airspeed;
#3.) An increase in available power on takeoff.
As mentioned above, the filter media itself is reusable. You just clean it and recharge it (coat it with oil so the dust sticks to it) once a year during annual and you can reuse it up to 25 times or 2,500 flight hours.
Since the Challenger system significantly improves the intake side of the engine at a very reasonable cost, we consider it to be the perfect complement to our Tuned Exhaust System which significantly improves the exhaust side.
Designed by Roy Sobchuk and manufactured by Maple Leaf Aviation in Canada, this easy to install fairing is part cosmetic enhancement (streamlines the appearance) and part performance improvement. It slightly reduces the drag of the tailpipe, but more importantly it creates a venturi to improve the air flow through the cowling for better engine cooling / lower CHT’s. The STC and installation instructions are included.
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 aircraft. 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.
