Background: In close cooperation with Maule Air, Inc., Power Flow Systems, Inc. (PFS) has developed a new Tuned Exhaust System for the 4 cylinder Maules. To get the best possible results required essentially a "clean-sheet" design to fit our system inside the tight confines of the Maule's cowling while accommodating the necessary exhaust tube length for maximum performance.

The exhaust and certification are currently planned for all Maules configured with the Lycoming O-360 and O-320 engines (both landing gear configurations.)

Due to the unique design and relatively "select" market group, we do not want to fully commit to the high cost of obtaining FAA certification and the fabrication of production tooling unless a significant number of Maule owners commit to the purchase of the resulting STC'd Tuned Exhaust System. We have developed a pre-production deposit agreement that is intended to reward those Maule owners who are willing to work with us to bring the project to fruition with a significantly lower net price for the STC'd Tuned Exhaust System for their aircraft.

Because of the high costs of FAA certification and production tooling, the exhaust system has a projected Price of $4,895.00. As Power Flow has done successfully with two other "limited market" airframes (The Cessna Cardinal RG in 2008 and the Aviat Husky in 2010), we are willing to devote the resources required to complete the FAA STC process AS LONG AS a minimum number of Maule owners (35) are willing to commit to the purchase of the exhaust system after it is certified. As an example, we went to the C177RG owners and asked for 30 commitments (certification costs were lower in 2008 and the potential market was larger). We had 54 commitments by the end of the pre-STC offer period! Five years later we have shipped over 145 C177RG exhausts worldwide, so the program can really work out for everyone's benefit.

We are looking for at least 35 owners who would commit to buying an exhaust system at a discounted price of $4,395.00. A contract would be signed and would require an initial deposit amount of $750.00. Another payment of $750.00 is due when the FAA project number is assigned. Once the FAA STC is issued, an additional $1,500.00 is due, with the balance due upon shipping.

We are offering increased discounts (to a maximum of $800.00) as additional deposit holders commit before December 31, 2014. The more orders we have, the lower our risks become and the more money everyone can save. The number of deposit holders is published on our website and we will have periodic updates on the status of the program.

We will begin the certification project as soon as we obtain 35 signed, deposit backed commitments. The Pre-STC discount offer will be valid until December 31, 2014, and the final discount amount will be based on the number of signed, deposit backed commitments we have on that date.

Our Exhaust systems have always had a no hassle, 60 day, money back guarantee. Skepticism is healthy - we put our money where our mouth is. If a customer isn't totally happy, they can return the exhaust system for a complete refund of the purchase price up to 60 days after first flight. We aren't aware of any other modification company out there that will do that.
