I agree. Custom Ducts are great. I have flown with them trouble-free for 12
years now and finally just ordered a replacement set due to wear and tear
over the years. As Bob said, the lengths needed may well vary for each
builder. For my set up, for instance, I ordered SCEET 3# diameter tubing
with reinforced ends. Total length on the copilot side was 11.25" and on the
pilot side was 10".
