heater boxes/muffler opinions?

[wjdesbrow]

I have a 72S Targa that is in A+ Driver condition -- all original with the exception of refurbished interior and rebuilt engine to original specs. I am planning to replace my heat exchangers and muffler. I have heard arguments both ways on the exchangers: standard Dansk (?) reproductions in cold (?) steel vs. SSI stainless steel. (My plan is to drive the car no more than 3-4,000 miles per year in no-rain, no-snow weather, and occasionally show the car in local/regional PCA events.) Should I save a few hundred dollars (and stay more "original") with standard steel boxes, or invest for the longevity of stainless?

Also, I have read where some enthusiasts use "jet hot coating" on new heat exchangers and mufflers. What is that and are there advantages/disadvantages?

Thank You.

Go standard, most will say ssi's but it sounds like you don't need them.
Jet hot, I would not bother. I had a muffler ceramic coated and it scratched so easily that it was not worth it in my opinion. It has its place, but I really don't think one is mufflers unless you have a turbo.
