Exhaust heat management

This fairly low-cost solution can offer minor reductions in heat loss.

It is often applied by brushing or spraying from an aerosol onto the exhaust system, followed by curing in the oven to allow the paint to adhere.

They can offer small performance benefits [1] due to the low thermal conductivity of the ceramic compound.

Often sold as a cheap and easy way to boost horsepower, exhaust wrap does not increase engine output much.

The far cheaper option in the short term is heat wrap being quick and easy to apply.

Ceramic plasma-sprayed coatings also have similar performance benefits and whilst being quite expensive and requiring professional application, they last a long time and protect non stainless steel manifolds from rust.
