    Is that hard coating for the exhaust something that is commercially available for the DIY'rs?

If a crack occurs there water can get into the engine and then it goes boom. The hard coat is an upgrade from the removable heat blankets which can collect oil and also disintegrate over time.

    I dunno. I inherited it. Very hard, very impervious to everything I’ve thrown at it.

    The key phrase here is

    "Hard wall exhaust lagging".

    Some reading when you Google that.

    From what I am reading it is fiberglass reinforced resin.......

    There's also some pretty cool metal covered stuff.....

    My pleasure...... On a side note I saw a Cummins re-power of a 53MY today. Very nice installation. Except it caught my eye that the water entered the elbow at the top.... not down stream. Learnt that right here on HOF. Sales dude suggested to "just replace them regularly"..... LOL.
