OK, I could not knock the baffles out with a steel rod or heavy screw driver. I do not think these are just simply tacked. I had to drill holes around the baffle and use a big flathead to knock out the metal in between the holes I drilled to remove the baffle. This makes getting the 3rd completely out near impossible as far as I can see. The jagged outter rim is left from the 2nd baffle. Any ideas what I can do to remove it except for banging on it. I have a slight bump in my exhaust pipe now because of trying to hammer the baffle out. Luckily it is not noticeable. Any suggestions would help. Thanks
