wat yall think about exhaust wrap?

im thinking of wraping my shorty headers since they are off my motor, so do any of yall have any reviews about it?

sounds very easy to install and will work right if installed right

i already have a pack of 1"- 50 feet and ill probaly have to buy another one but first im going to use the one i have to see how much i would have left. I'm going to start on it 2day after i get out from work

 

Its good stuff. It keeps heat in the headers and makes the exhaust flow faster and keep temps under the hood lower.

 

cool well i just posted sum pics of it on my thread of my rebuild. i think it came out good for my first time doin it
