This has plagued me with Hurricane #6. What really pi$$es me off is it started right after I paid $300 for ceramic coating. The baffles were merely tack-welded inside the pipes and those tacks have broken loose. I stuck a camera inside and the broken tack was barely 1/8" in size, not nearly enough for this application. I tried the screw trick and that didn't work long term. I don't want to cut and re-weld the entire circumference of the pipes, so...in the next couple of weekends, I am going to do what Wrench suggest above, hopefully for the (*&^% last time.
