Tom,

I bought a carbon pipe for my Hanno from ES Composites. It is a carbon version of the venerable Hatori 650. I ran it on the bench to get the setup right and then ATTEMPTED to install it in my Conquest. Turns out it is too long to fit my plane, so I have a beautiful 60 size (very) quiet pipe that I cannot use. It weighs just over 2 oz, with carbon stinger. I paid somewhere north of $130 for with shipping. It might be perfect for your YS 110. If interested, please contact me. [email protected]
