You two sound that know each other well.
Is it grammatically correct?
Should know become knowing?

"You two sound like you know each other well."

Or

"It sounds like you two know each other pretty well."

In formal English, substitute "as if" for "like". (But many of us "old folks" were brought up to use "as if" even in everyday speech.)
