Does anyone know of a mail order source for the THORLEY (?) headers that I
have been reading all about?? I need to rework the exhaust system fron
Cylinder heads to bumper. Also looking for source for Stainless y-pipes and
other parts neccessary. I have just subscribed to GMCMM and Cinnabar's
newsletter, so I don't have any back issues for researching the Ads. Thx.....th

Here is the information you requesyted. I bought from them last week
headers arrived in 5 days. hope this helps.

Webb address is: "PRO-MAX PERFORMANCE"

If you are doing Thorely Headers you might want to go the extra step and
have them ceramic coated. This can be done by Jet-Hott and a number of
other companies. It keeps the radiated heat way down and is worth the
extra $$. If you want to go that route you need to get the headers
with out the chrome plating. I know Thorely makes them that way and
that Pro_max should be able to provide them.

>From everyone that I have talked to they advise against having the headers
coated. The reason that they run hot is that there is to much backpressure,
same reason that the original cast iron headers warp. Put the money into a
3 inch y pipe and tailpipe and that solves the problem. Also adds about
40HP with the headers.

Well, I have the 3" exhaust from Jardine and the headers. The idea
is to keep as much heat in the exhaust pipe so that the heat and exhaust
are drawn out at the tail pipe. The ceramic coating does this and
also allows the engine compartment to remain cooler. The compartment
already has a heat problem. Before having mine coated they were very
hot (red glow at night). I had mine done by Swain Coating here in
Rochester and now I can almost touch them and not get burned. What I
had done was overkill as this stuff is used by the Air Force, NASA and
Nascar but he is close and it was easier than sending them to Jet-Hot.
Swain does not look as nice as Jet-Hot but is more effective and a few
more bucks.

If I ever do an engine I will have them do all the internals, such as
the bottom of the manifold, tops of pistons etc. The new ceramics can
control heat and friction in ways that were unknown in the past. Most
major racing - F1, WSC and endurance engines use the stuff and along
with
new syn oils the engine self destructing has gone way down. It truly is
overkill but all I want is the GMC to go like a Cobra, ride like a
Mercedes, and handle like a go kart. My wife says "OVERKILL" is my
middle name.

As I understand it, thermodynamically speaking, the principal is that
the hotter exhaust gas can be kept, the faster it will flow, which leads
to more complete expulsion of the products of combustion in the engine
and consequently less back pressure. Thus, exhaust tubing that is
ceramic coated is more efficient in retaining the heat of combustion vs.
uncoated tubing, which radiates or loses heat.

Exactly what I was trying to say, but Paul says it with such elegance.

Marcus, et al:

Another thing I should have discussed about ceramic coating is that it
provides longevity to the exhaust system.

When I decided to get my headers, etc., coated, I was looking for
longevity (don't want to have to replace exhaust system components a few
years down the road due to corrosion/rusting out) as well as a reduction
of heat in the engine compartment.

Some individuals claim uncoated headers increase engine compartment
temperatures, while others claim the opposite??

I understand that the coating put on the Doug Thorley headers during
production, is a cheap nickel coating. After use, it starts turning
colors and even rusts.

You can save a little money by purchasing the headers uncoated if having
them ceramic coated. Otherwise, the coater will need to sandblast it
off prior to coating, which costs extra.

Had my coating done at Hi Performance Coating (HPC) in Salt Lake City.
They were able to coat both the inside and outside of the tubing.

As a matter of fact, I got the best price on the headers from HPC with
the added advantage of saving cost shipping them to HPC.

Paul,

Do you have an address or phone number for HPC in Salt Lake City?

How much for the headers and how much for the coating?

Thomas:

Invoice was $490.00 (no breakdown of costs) plus shipping.

As I recall, coating was ~ $215.00.
