Heat Shielding

[Jaxonalden]

Check this site, ( http://www.thermotec.com/ ) I use it on a number of applications. Wrapping your headers will cut down on under hood temps on conventional cars. Ours on the other hand will not because our exhaust exits down into the airflow under the car. Wrapping will keep the exhaust header hot, which will keep the exhaust hot, which will keep the exhaust velocity high and will increase cylinder scavenging.

Personally, I've always been leery about wrapping headers on a street car. Most people wrap their headers in an attempt to manage a heat problem. The arguement for better scavenge effect is all but moot until the tach is pointing at 1-o'clock or better.

In reality, all they're doing is forcing the issue downstream. I've seen many cats fail prematurely on cars using header wrap. Something to consider at least.
