The Power Flow Tuned Exhaust System is not just a replacement - it is a vast improvement over the stock Cessna 172 exhaust system.
The concept is simple, out with the old exhaust gases, in with the new fuel-air charge. By more effectively emptying each cylinder of spent exhaust gases, Power Flow gives your Skyhawk a number of significant benefits:
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 :
The Power Flow is a versatile, quality constructed, complete replacement of the entire exhaust system on your 172. A new Cabin and Carburetor Heat shroud (utilizing your current SCAT tube hook-ups) is included. The entire system is constructed from 321 stainless steel and includes minimal structural welds in the cabin heat section for improved safety.
All necessary parts are included for easy installation, usually requiring just 3 – 5 hours. The system can be installed by one of our Authorized Dealers, by your local A&P / IA, or you can fly to us for the installation. Fly in with a standard Cessna 172 Skyhawk, fly out (usually the same day) tuned for maximum performance and efficiency.
Our industry leading 60 day money back guarantee means that if for some reason the performance benefits listed above fail to materialize on your 172, 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.

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:
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.
Part cosmetic (streamlines the appearance) and part performance, this option 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 and lower CHT’s. The kit comes complete with STC and simple Installation Instructions.
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.
