[edit] Header wrap

Header wrap is material used to wrap around headers to reduce radiant heat.

[edit] Header wrap pros

Claims made by header wrap manufacturers (subject to bias: need to be verified or debunked):

  • Helps retain heat in the exhaust system, which maintains hotter exhaust gases, decreases density, and allows exhaust gas to exit faster.
  • Promotes greater exhaust scavenging and lowered intake temperature, which leads to increased horsepower.

[edit] Header wrap cons

  • May void warranties of header manufacturers.
  • Holds in so much heat that the header metal fatigues and cracks.
