Well, I must be that 1%'er out there..... 'cause I (properly) wrapped my header & love the perfomance result.....
(2) coats of VHT Hi-Temp applied to a warm pipe.....
then Tightly wrapped with fiberglass tape- 1st the header, then the collector.
Finish off with @ least (2) coats of Black Silicone sealant over entire pipe.
I can truly feel the difference  .....no more "warm leg" syndrome & all the spent exhaust & heat goes out the back where it's supposed to.....
