Is that second to last photo a HIGH OUTPUT D8?

Looks like it with the twin stacks. I don't know if there is any other outward identifing items.

Other identification points are missing:

1. Should have an extended hardnose, about two extra inches to accommodate the balancer on the front of the crank. You can identify from photos because the hood has an extension on it.
2. A small point, but should have a V-tube precleaner, with two precleaners vee-ed into the one air filter stack.
3. The air filter is a bigger diameter than a regular 2U.
Not visible in the photo, but another spotting point: Top corners of rear case drilled for about 1" allthread with nuts on front and back of case, to put tension on case and counteract stress from extra pinion gear torque.

I'm pretty sure this is a regular 2U who's exhaust collector Y-pipe has rotted or broken and been fitted with two stacks.
