Old Exhaust Shower Head

Well I guess that answers that. Thanks Robert.

That said, the link I posted a while back and other exhaust-related articles on my blog show how D'angelo does it. I used the same approach. Make it so water absolutely cannot get back into the engine, and you've done it right.

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

The water is injected directly into the showerhead instead of water incasing the entire part, so it's all downstream towards the outlet. The hard coat insulates the part, the main advantage is that the water is kept away from the joint next to the turbo/manifold. 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.
