I added it to 2V because got no response from 4v. It's a Cobra, I"m just looking for a slight heat reduction anywhere in the engine area and anywhere i can, when I can.
I'm using stock manifolds, the downpipes and cats are all sealed with high temp coating and a rust prevention coating I've been using in the mechanical field for decades.
So, from what i gather, this wrap seems to be useless.
-Thanks for the responses.
I will take temp readings before and after I do the work just to see what happens.
