Reply to "header insulator"

I called www.jet-hot.com and was quoted 480 bones for the entire exhaust system, both headers and the muffler assemblies. $230 for just the headers or $250 for just the exhaust assemblies. I'll end up saving on freight by shipping them all at once. Their closest plant for me is in the Phoenix, AZ area. Freight is about $60-70 round trip. They'll get the job done in 3-5 days.

I'm going with their 'Sterling' color. Looks like chrome or polished aluminum or Stainless Steel. I think it'll look really tricked out when it's back on. They can mask off the chrome tips so they stay chrome.

The procedure is to 'sandblast' them with aluminum oxide crystals, inside & out, then apply the coating(s). The inside is 'all or nothing' and I guess I'm gonna go with inside & out for the headers and only the outside for the muffler assemblies because I have those silencers inside the four (4) tips of my exhaust pipes.

Jet-hot Coatings not only insures no corrosion and excellent looks, but also runs "alot cooler, and not just by a few degrees" so this will keep the area around the carburator cooler and thus running better. It will also keep the car's interior a little cooler.

Jet-Hot Coatings is sending me a box to ship these parts in. And I'm gonna try and ship them out on Thursday, July 3, 2003, to get this done.

To prepare the surfaces for coating, Jet-Hot forces their sandblasting material through the tubes (as well as sandblasts the exterior).

My question, and I only have two (2) days to find an answer, is:

(1) Is it a good idea to sandblast the interior of the exhaust/muffler assemblies, given the fact that I have the silencers inserted into the tips of the four (4) exhaust tips?
It would make that part of the exhaust system run a little cooler and prevent possible corrosion.

(2) Is there any packing material such as fiberglass or steel wool or even asbestos behind the four (4) perforated silencer tubes?

Thank you.
