xi question

I have an 01 325xi 5 spd with 89k. When I shift normally there is almost like a banging sound when I push the clutch in, switch gears and its especially noticeable when i let the clutch out. The only time i dont hear it when shifting is when I'm real easy on the clutch. When I get on and off the gas I can also hear it. What could this be? Is there anything that I could replace or tweak to stop this?

I searched for this but couldn't find anything.

Thanks in advance
