Knock when engine is warm.

Engine has a knock to it once the car warms up. There is no loss of power, oil pressure -seems- fine. Could it be the exhaust? At least thats what I hope it is. Knock does increase with RPM but gets drowned out by the exhaust sound.

Can you post a video of it perhaps?

Exhaust leaks can sorta sound like a knock sometimes. Definitely check for exhaust leaks.
