I have a 2002 Dodge Ram 1500 Van. What would be the best way to reduce the under hood exhaust heat? Thought about ceramic coated headers, but there are no full or mid length avail for my application. Not sure shorties are worth $400. Is there a do it yourself coating available for the stock manifolds, or can they be wrapped with exhaust wrap? This is not about looks at all, just reducing the heat under the doghouse.
