I know Captain Chris is replacing his throw-out bearing soon in his Cobra. You might wanna talk to him. He said he's getting sound more when the clutch is engaged though.
From my experience throw-out bearings usually make noise when the clutch is engaged (foot off the clutch pedal). Could be something else if you're hearing a noise when you disengage the clutch.
Well I was able to take a look at my exhaust yesterday and everything looked tight. Going to bring it into the dealership to have it looked at while I'm getting my free oil change. It seems to be making even more noise now. :(
