Ron Main sent this to me a few days ago -- and I just now got a prod in the backside from Sparky, who told me I should get it posted. It's sort of an ad, but it does give good information about the heat shielding on the #715 exhaust system.
Advanced Alloy Shields has just gift wrapped our Twin Turbo exhaust system
with a note! Do not unwrap till after “SPEED WEEK”
Advanced Alloy Shields™ custom manufactures reusable hard cover thermal insulation systems that are molded to fit directly over hot engine components, up to 3000° F. (1649° C.). Since 1972 we have worked with military and aerospace industries and is one of the most qualified companies for extreme heat control
You will see Turbo Insulation Shields on nearly all professional racecars with turbocharged engines. Why? Because they help to increase engine performance and protect against the damaging effects of radiant heat.
Exhaust gasses power the turbo spindle; the higher the performance of the engine, the hotter the exhaust temperatures will be. In fact, if you were to open the engine compartment of any high-performance vehicle after it has been driven hard, you’d see a glowing red exhaust-side turbocharger housing.
To avoid damage and sustain optimum performance, it is important to protect the rest of the engine from the 1600 F°+ temperatures that radiate from the Turbo. Covering the turbo housing will also promote cool air intake that translates to increased horsepower and fire protection!
This is when you should look at the first photo.

Our Advanced Alloy Shields are made with two layers of
Inconel with 1/4" inch blanket of 3000 degree rated Silica
insulation between the two layers of the welded Inconel panels.
