Beware, Honda does NOT offer an extension to make it easier to drain your oil. Also, if such a device has been installed by the manufacturer like that it is highly probable that Honda will void the warranty because it is not one of their parts.
The reasoning behind it is that they have tested their crankcase oil plug to withstand the total environment their engines work in. Fact is Honda requires manufacturers of any product with their engines to be tested and approved by them for the application. Any extension to the drain opening, including the extension hose/pipe and valve are not Honda parts.
If properly designed for after sale service there should be an opening in the base that will allow you to place a container to collect the oil. With luck the spread will be minimized and clean up reduced. You can get high temperature hose and a needle valve from an automotive supply store to allow you to put your own extension on; BUT it may void Honda's warranty.
Hope this helps? Cheers.
