Has anybody used a set of headers on their coach with success. I have talked with multiple FMC owners who tried them with no success. Coach #412 had paperwork to show it had a set on it then a new set of manifolds after that. One owner (Udo Horn #947) said he knew every wellding shop from the east to Utah. I am using a different style of exhaust manifold (low manifold pics in albums) to get away from cooking my valve cover gaskets. Have not had a chance to drive the coach with them yet. Under a couple feet of snow right now.

I asked Ron Herbert about his headers and here is his answer:

"About 10,000. No signs of wear. They were custom made by Stanley's Exhaust here in San Clemente. --Ron"

I have used headers on my Southwind coach, but have had bad experiences with many.
BANKS is the only brand that I had success with. They are SST, thick, and expensive.
The mounting flange of the BANKS is 5/8" thick. I don't remember the gauge of the tubing, but I think it is thicker also.

I had mine JET HOT coated, but I don't think that the coating did any good at all. It is basically a very high temperature paint (.002" thick or less).

SWAIN TECH offers a thermal coating called "White Lightening" that is .015" thick. It is only applicable to the outside surfaces (unfortunately).

EXHAUST WRAP:
BANKS, like most any header mfg. will tell you that using exhaust wrap will void any warranty on the headers. The reason for this is that exhaust wrap really works! It SIGNIFICANTLY reduces engine compartment temps, but keeps that heat in the exhaust tubing. This can overheat the metal. SST material on the tubing will help in that it is more resilient, but still all metal has it's limits.

Another company, (Sanderson?) makes a cast header-like manifold that is much smoother than the "log style" exhaust manifolds typically found on V8's, but they are expensive.

I can back up what Jerry says about the wraps. Several members of the Aero Cruisers (which have I360s in them) use the wraps with success, but only from the exhaust pipe down. Not around the headers. If burning the plug caps is a problem, you can get shields for those from any auto parts store.

Yup---Wrapping the headers---even the stainless steel ones---is disasterous as the heat has nowhere to go---until it hits open metal---where it blows holes right though---Pictures attached--
