Hi,

I will be using a YS-160 DZ on my OTOP. Now I need to order the extra bits and pieces such as Hyde mount, manifold and pipe. I would like to ask the OTOP owners what kind of manifold/pipe setup they use with OTOP. The plane has the pipe mounts aft to the fusellage I don't know whether I could use the Hatori short pipe in such case?

- Do you use a short pipe or long pipe with OTOP?

- I am leaning towards Hatori (HA 821). For this pipe there are two options for the manifold, 1) Manifold HA822 which locate the pipe in front or 2) Flexi manifold which is longer so that the pipe is located towards the centre of the fuselage.

- What is the difference between HA 725 and HA 821? They are suggested for use with the 160 but which is more suitable for that particular application really?

I really look forward to your suggestions. If you have any photos from your setups please send some.

Thanks in advance,

Nikos

PS: Inputs from non OTOP owners but with experience on YS 160 muffler setups, is more than wellcome.
