[W126 Coupe] Exhaust coatings

[Calvin Young]

What do you guys think of this logic?
   
  
The theory of insulating the exhaust system to retain heat is commonly overlooked by most racers. After heat has performed its function in the combustion chamber, it travels out the exhaust port to the header. If the Gases are allowed to cool, they lose velocity and the scavenging effect is reduced. If by insulating the exhaust system, gases inside are kept at the highest possible temperature, the resulting effect is a greater exhaust gas velocity and higher efficiency. Each gas pulse moves through the pipe faster, making room for the next and pulling it along. This reduces back pressure and increases the "super-charging" effect created by the now of high velocity gases.
Insulated headers also reduce radiant heat and lower underhood and cockpit temperature. By reducing air intake temperature 10°F, a horsepower increase of 1% results, a 30°F drop equates to a 3% horsepower increase. This is inexpensive horsepower.
Swain Tech engineers have developed several heat management products for use on headers and exhaust systems.
