Bolt-on a Power Flow Tuned Exhaust System and give your Skylark that shot of extra “oomph” that you know it needs. See it, Hear it, Feel it, Try it - we give you a full 60 Day Money Back Guarantee. This boost of power will have you flying higher, faster, and on less fuel in no time, with only one side effect: a chronic & infectious ear-to-ear grin.



The Power Flow Tuned Exhaust System is not just a replacement - it is a vast improvement over the stock Cessna 175 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 Skylark a number of significant benefits:

  • You will immediately notice an increase in RPM (30-130 more).
  • Significant improvement in rate of climb (100 - 300 fpm).
  • You are in control: Want to save fuel? You can use less throttle to fly at your current cruise speeds and save from 1/2 to 2.2 gallons per hour.
  • For more power, use the extra RPM (100 RPM yields approximately five extra knots of airspeed for an additional 1/2 gph in fuel burned).
  • 175-C Models with the Constant Speed prop get the “best of both worlds”: Improved take-off and climb performance PLUS cruise speeds that are 3 – 7 knots higher.
  • The Service Ceiling on your 175 will increase by 2,000’ to 5,000’, with a corresponding improvement in safety margins in high Density Altitude environments.
  • CHT’s are reduced by 10O F – 20O F with less difference between cylinders.


    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 for your Cessna 175. 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, or you can fly to us for the installation. Fly in with a standard Cessna 175 Skylark, 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 175, 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.

    “Classic” or Short Stack?



    The Classic is our original design from 1999. It is the “ideal” tuned length for this engine. Everybody loves the performance, only a mother (or an engineer) could love the looks.



    So, we came up with a compromise: The Short Stack is virtually indistinguishable from the stock Cessna exhaust and will give you about 85% - 90% of the performance gain of the Classic in a much more attractive installation.

    

If you operate on floats, frequently fly in high density altitude environments, or simply want the best possible “Bang for the Buck” we still recommend the Classic. Otherwise, you will be well-pleased with the performance boost you get from the Short Stack.



    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 Skylark’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. 

    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.
