I had a noise in mine and it turned out one of the tac welds had come loose inside, holding the baffle. I drilled a small hole on the back side of the pipe (baffle area) and screwed in a stainless sheetmetal screw long enough to catch the baffle. Tightened it down and took care of the problem. Wasn't my original idea, some posts about 2 years ago on here suggested it.
