Davo and I are looking at getting some exhaust wrap and wraping the manifolds and exhausts of both our cars in it.
Question is, on my car, would it be beneficial or a hinderance? There are two schools of thought
1. Heat is kept away from the engine and the air in the engine bay keeing everything cool
2. Heat is kept in the manifold and turbo and not allowed to escape making them even hotter and increasing the risk of damage.
Are they both right?
