The concept is simple, out with the old, in with the new. By effectively evacuating each cylinder the Power Flow is capable of giving your Cherokee a 30-50% increase in climb. You will also notice an increase of 30-130 more RPM during takeoff, climb and in cruise. Want to save fuel? You can use less throttle to go the same speeds and save up to 2.2 gallons per hour.

The Power Flow is a versatile, quality constructed, complete replacement of your entire exhaust system. You are in control. For more power, use the extra RPM. For fuel savings, throttle back and fly your pre Power Flow airspeeds. The entire system is constructed from stainless steel and includes minimal structural welds in the cabin heat section for improved safety.

All necessary parts are included for easy installation. Our customers report an average install time of between 5-7 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 install. Fly in with a standard Piper, fly out tuned for performance.

Each exhaust system includes an unconditional 60 day (from time of installation) money back guarantee. If you are not totally satisfied, for any reason, you can return the system for a full refund of your purchase price (Refer to Shipping/Return policy for details).
