Header Wraps

I see a lot of different temp ranges from all manufacture's for all kinds of crazy money.
What would be the sane temp range for our street cars? I doubt we need the 2.5K temp. wrap LOL.

Header wrap is a major NO NO on a street car. It will cause your pipes to rust out quickly. Get your headers ceramic coated. Yes, it's expensive. Yes, it's worth every penny. I had my headers done in CERAMAKROME, and ten years later they still look great. No extra insulation under the hood, I can put my hand close to them with the car running.

Two doors, four doors, wagons, and ragtops.

I agree, ceramic coating is the way to go.

x3 on ceramic coatings.

I gotta say that the wraps work too, but the rust potential mentioned above is (as I understand it) really only going to be a problem if you drive your car in the rain. The wrap can hold the water against the thin header piping long after the motor is turned off.

Allan is correct. Wrapped headers can cut under hood temps down 40%. But they due collect moisture and not just from rain off the road. Every day they will absorb moisture from the air as condensate.

Back in the day the "hot" set up was white header paint. , red boots, yellow wire and a blood red Vertex, or a beige Accel distributor (as MSD hadn't been brought together yet). Big Dave

PS. :-) Gotta also add that the header wrap on my Kawasaki ZX-12R is good for 201.91mph!


...good point on the humidity factor Dave.

Here is what I used on my bike. (I just like the brand)
http://www.thermotec.com/products/11...ting-wrap.html

Looks like they are rated to 2000 degrees, but I thought the pipe itself only got to 800 on a normally aspirated engine. (varies by engine, parts, design, etc)

Stainless steel pipes on the bike, right?

Yes I believe it is Jay, but I'm not sure what grade/quality it is.
At one point I had a titanium pipe,.....but I think that was an Akropovic on my last bike.

I didn't really have any rusting concerns and I don't ride if its going to rain.

If the bike goes 201, I'm sure you won't have a problem drying out the pipes!
