I am thinking about the CAT surgery on my M3W. There was mention about some sort of glue in the joint between the header and the muffler. What method was uses to separate the two parts?
Also, I went ahead and took a photo of the baffle(s)
I tapped around the joint with a small ball peen hammer and gently opened up the joint just enough to break the seal (not much is needed) with a small flat head screw driver and a lot of finesse. After that, it was a matter of wiggling the two pieces back and forth for a minute while pulling them in opposite directions. It will give way, it's not that much sealant. Also, I didn't feel the need to re-seal the joint when I put it back together. It doesn't leak at all after it's re clamped, but I guess that's a matter of personal preference.
We just did my father in laws M3W the other night.
