    Replace with a Tubi or Capristo, and rip the cats off it while you're on.

    On a 355 it would tend to indicate the headers had blown through & would need fixing pronto before valves start burning. Not sure if the 360 is prone to the same issue - probably worth a good poke around.

    You are correct but the 360's really haven't had a header problem. Almost every 360 with a stock muffler has had this problem given enough time.

    The only cure is a different muffler(Tubi).

    Haven't got the problem with the Tubi - you now it makes sense !!

    How does the white dust get in the engine compartment if it's coming from the exhaust ?

    The muffler is a big insulated can. The part you see is the outer layer, like a Thermos bottle. There are seams and the insulation leaks out of them. Look at the muffler cold and look again hot. You will see witness marks that show about 1-1.5 cm expansion width wise. During the expansion/contraction cycle the insulation works out between the expansion joint.
