Cracking exhaust noise 85 GS550ES

[Danjal]

are the 4 into 1 a one piece construction and welded where the headers and the can all meet up? I know my buddie V&H are two piece and the can just slips over the headers..I suppose that if its suckingb air there it could casue the same syptoms.. How about the baffles? They in or out?? could be a few things at this point. Got a good seal at the head and the pipe headers???

The 4-1 is all one piece, and it ends right under the backside of the motor. After that the muffler is one piece with a pipe coming off of it the rest of the way. Its not welded where those 2 individual pieces meet up. The 4-1 is completely welded together, and no cracks/holes of any sort.

Give me a few mins and I'll snap a picture of it.
