I have a question about Exhaust
When you exhaust champions like 
in his ult, will the attack speed slow still procs?

I believe Yi is immune to attack speed slows during his ult, thought I saw riot mention that somewhere.
Because Exhaust is essentially one debuff Yi's R effect of ignoring slows ignores the entire debuff.
tldr: Yi's ult ignores Exhaust completely.
