Exhaust Wrap

Exhaust Wrap

I picked up some exhaust pipe tape/wrap (header wrap). It is an insulation material that you wrap your exhaust pipe and manifold up with to keep the heat in. It's costs about $50 for a 2 inch x 50 foot roll. It serves two purposes:

  1. Keeps the underhood temperature lower. Engine runs cooler and cooler air to the intake. Supposed to make underhood temperatures lower by 50%
  2. Keeps the hot exhaust gas in the exhaust pipe which increases the exhaust gas speed providing better scavenging of the cylinders during the exhaust cycle. Engine breathes better. Supposed to be good for 2 or 3 hp.
