added a couple pictures

apparently along with #1711 ZS-JZK there are now two Helios flying in South Africa.

Edit: added another pic (opened above) just because I have it, and because it shows the conversion to NACA air inlet on cowling something I liked the appearance of, not sure why it is on left side. I intended to do the same one on each side but never completed, in fact I bought the inlets I believe the inlets are in a box in the garage. It also looks like the landing taxi lt opening has been modified, not really sure why exhaust has been changed unless there is a muffler inside those larger tubes .

Another Facebook photo found at Stephens page it is a left side view and a mod to the fresh air inlet appears to had been moved from cowling to upper vertical on boot cowling this probably makes the ducting easier and is probably worth doing. On the right side I personally prefer the appearance of the Naca inlet for the heater air inlet.

another thing I noticed is the large size of the exhaust opening in the photo of the muffler system on this Helio makes me wonder if it is something like the 'Powerflow' tuned exhaust placed on Cessnas, that exhaust gives the Cessna a 10-15hp boost. I believe the Helio factory's early exhaust system on the H-391s was tuned and probably gave a small hp boost, because it had equal length stacks going into to an expansion chamber the mufflers themselves.
In comments by the photo, Grant Timms says he just flew this Helio. Who is Grant is he an owner or does he know anything about the exhaust system?

Any out there know anything about this exhaust system?

I found a picture of ZS-JAR in flight so thought i would add it just because.

Anyone know anything about this Helio, the exhaust system in particular?

I opened it in the Photo queue above.
