Max Lefroy VH -KHC Cessna 172 Skyhawk 180 Penyang converted"I have been very pleased with the additional performance of the powerflow system.
The aircraft now climbs at 900fpm (previously 600fpm) @ 80 knots and cruises on 30 litres an hour- a fuel saving of 7 litres an hour.

"I get asked quite often about the "funny" exhaust protruding out of my Cessna 172M. It does look a bit different, but it does work. Two years ago when my old exhaust finally died, I decided to put on a powerflow - in fact I was the first one in WA to do so.
At first the cost was a bit of a jolt but I got over that quickly when I started to understand the benefits.
The first thing I noticed was how quiet it was on start up (which is the case on all power settings) - however reduction in noise does not save money but it was pleasant. The gain for me was in the extra power that was there - how much in technical terms is hard to guage but when taking off from a farmers paddock with a load, that extra power can be felt quite dramatically!
ONE DAY IT MAY EVEN SAVE MY LIFE!! Fuel savings I can be a bit more technical about as I have flown a round trip to a country town in the wheatbelt hundreds of times over the last 7 years. That trip used to require 58 litres (give or take a 1/2 litre) it is now down to 51 litres which at the current price of avgas is a nice bonus to the other benefits.The more hours the plane does the cheaper it gets - not forgetting that to put on an ordinary exhaust is not cheap................................."

"The Powerflow Exhaust gave me the confidence to repitch the prop form 58' to 61' on my cherokee 140 cruiser (160hp).
I have now done about 20 hours since fitting and I am really pleased with the performance. I now cruise at about 117knots T.A.S. @ 75% power. That's a gain of about 10 knots!! The aircraft takes off in a shorter run and climbs better(more rpm). Fuel consumption has decreased and I am saving approx 3 litres per hour (more if I run it at a lower power setting).
With the muffler in front it is even quieter in the cabin than before. Thanks to Shane at Restorair."
