I used the silver to wrap all the sides of my old STI tmic and Y-pipe .
The turbo side seemed to stay much cooler to the touch after spirited driving.
No real numbers to back it up, but the hand warmth test showed some differences between wrapped and not.
No real pictures, use your imagination, just a really shiny tmic.
I also use the tape to keep the exhaust on my ATV from melting plastic parts, to keep heating lamps for critter cages from melting stuff, fix leaks in AC vents. I find it to be quite useful.
I can definitely say the heat reflective tape works in a lot of situations, hell I made a patch out of like 5 layers to cover a hole in a mid pipe, held for the better part of 6 months and was hell to get off in the end.
