I've seen heat wrap used mainly on the manifolds of race cars where i understand it has a dual purpose of protecting ancillaries from heat but also to help the flow of exhaust gasses and thus scavenge a little extra power.

Is this correct,and if so would there be any gains to be had by using it on a road car?

Yes, that is the case, however the power side of things will only apply to those running highly tuned engines where optimum heat is required to keep at the ideal running temp.

Serves its purpose when pitting, slow laps etc, keeps the race temp heat in the engine.

Thanks for that,the engine is fairly well tuned but it would probably make very little difference to perfomance for road use then.

Plus the fact it would hide my shiney new manifold :D
