Message:
I bought some wrap for my JBA headers today, I hope the box of 50 ft is enough (the wrap is 2" wide). I know the performance improvements of wrapping the headers. But, since they are a little dirty, after I clean them should I paint them with high temp paint? They are JBA ceramic coated and have been on for 7 months and 15K miles.
I'll probably do this this coming weekend before my next trip the sunshine state.

Boomer, what is the benefits of header wrap? I know they lower engine compartment temps. Does that increase HP or what? I asked a month ago about getting ome for my headers but the general feeling from responces was it was a waste of time. Thanks for your help.

Boomer: NO! I've ruined several headers in the past with header wrap. That stuff is primarily for the seriously modified race vehicles...not a street driver with simple headers.

I was always told that header wraps are bad. The wrap keeps the heat in the headers and because of the excessive heat generated the headers may fail. I believe there is a better explaination of this at JBA's site. As for the ceramic coating on headers, mine seems to have heald up well for the 6 months I have had them on my genII.

I'm glad I haven't done this yet then. My future plans do include making this engine turn 400+ of all motor, then maybe, just maybe a super. That is if I can get that much power. So I guess I'll hold on to them until I make a lots-o-power engine, or sell em to my friend with a daily/drag TA.
The ceramic has held up since I put them on in April. No problems to report. They turned a light brownish color from the heat and mud. I paid 410 after tax, so I think I got an ok deal.
Thanks Everyone.

I have a 97 5.2 in my 4x4. I got them from
http://www.performancecombos.com/
I called them since they have a policy that they will meet/beat any competitor. So I called up a few other places and told these guys, so they gave me the deal.

Bernd,
So when should I wrap the headers? After I push 400+hp, or even more of a drag orientated truck. I'm using my truck as a weekend offroader. I need to keep the under hood temps down, that's why I considered doing it.

Boomer: It's not required for the street driver at all. Just stick with Ceramic coating.
On the Performance Combo's website...hehehe...i'm less than them already. Give me a call and i'll work out a package "deal" if you want.

Hey guys, according to a high performance custom header manufacturer, Sanderson Headers, they talk about header wraps:
www.sandersonheaders.com
"We get lots of questions about the thermal wrap products that are seen on various classes of competition cars. it's natural to assume that because racers use a product, it must have some performance benefit. The theory behind thermal wrap is that maintaining the combustion heat in the exhaust system improves scavenging. But on street driven cars any small advantage you might gain is offset by ugly side effects.
Racers don't mind replacing exhaust system components frequently -- you will. On street driven cars, you want to get rid of the heat. The higher the exhaust system temperature, the faster you'll burn out gaskets and destroy the headers, converters and mufflers. Unless you've got money to burn, our advice about using thermal wrap is DON'T!"
I just wanted to add that to provide an alternative viewpoint for street applications.

One more negative - header wrap will trap
moisture; sure, when you fire up your engine,
the heat will boil it off, but when you shut
down, atmospheric moisture will condense on
the header wrap (along with everything else)
and be absorbed into it. Your beautiful exhaust
system now is soaking in water - and we all
know what that does to metal!
