I finally gave into temptation and decided it was time to remove my baffle from the exhaust. I managed to remove the retaining screw, but the baffle would not budge. On closer inspection it seems that the bottom part of the piece of metal holding the baffle in place is stuck in some form to the inner rim of the outer can. No doubt the answer is blatantly obvious and I'm being simply ignorant, but can anybody offer any suggestions as to how I can remove the baffle with the minimum of fuss. My initial thoughts are to spray WD40 on it in the hope it will loosen it up.
