20 years in business & kudos from a customer

Happy New Year to One and All!

We are proud to announce that 2019 marks Power Flow’s 20th year in business and that we now have over 5,400 of our “Bolt-On Horsepower” Tuned Exhaust Systems installed and flying worldwide.  

Delivering a great product that meets or exceeds our Customer’s expectations is an important part of what do, but we truly believe that it is the service after the sale that really sets us apart.

We recently received unsolicited feedback from a customer whose Cessna 172 is used in a busy flight school and who needed a replacement part. He initially contacted us and told us that his technician would be calling or sending us pictures of the needed component.  But when a day went by with no follow-up, we took it upon ourselves to “close the loop”and called the owner / Customer back. We were able to figure out what was needed, sent the part out within 45 minutes and gave him our newly discounted UPS pricing for expedited delivery.

Here is what his follow-up email to us said:

Thank you very much for the help and responsiveness.  I mentioned to my mechanic that day how customer service focused Power Flo [sic] seems to be and its refreshing in this industry and quite frankly, society nowadays!  Appreciate the extra effort!

We are happy to have been of help to the customer and appreciate the compliment!

Incidentally the part needed is the only part in our exhaust system that is a wear item. For Cessnas with Classic systems, and most of our other exhaust designs with a 3.5 inch tailpipe, the tailpipe contains an inner assembly called the muffler insert.  

This sound chamber/cartridge consists of a perforated tube (2.0 inch diameter, welded onto a ring that is screwed into the base/aft portion of the muffler). We put a specially designed material consisting of two interwoven layers to absorb sound around the outer portion of the perforated tube so that the exhaust (and noise) comes down from the upper part of the exhaust and runs through the middle of the perforated tube, losing both velocity and volume as it goes.  

This allows a large volume of sound to be absorbed (and thus quieted) without impeding the gas flow so what we have is a “pass-through attenuator.”  Over time the sound absorbing material deteriorates due to its contact with the hot exhaust gases and it eventually disintegrate after about 400 to 800 hours flight hours.   Once this occurs the exhaust system gets louder but provided the inner perforated tube is still intact, it remains safe and legal to operate.

So how can we help you?
