Hey!


Been away for a while but not from flying. This little ultimate
is a great flyer. I will get you some pics of my ys 63 install with
MACS 90 and flex pipe. This set up is working extremely well.
It is just as quiet as the stock muffler and engine actually
gains about 100 rpm. It is mounted inverted so only the bottom
of the cowl has to be relieved.
Will have pics soon
