The guy that made mine was Levi....also known as Turbo Performance Products....also known as 1darkmax.
I have a blanket on both my turbos and he also made me one for the hot pipe that connects them.
I had my exhaust manifold ceramic coated by PolyDyn and intended to do the piping and exhaust housings the same way....but I noticed that even with the ceramic coating the heat coming off the manifold was still incredible. I actually burned myself one time at least an hour after I killed the truck....took some skin right off. LOL
That stuff not perforing like I wanted got me to looking at other options and I ran across Levi through another company....he made the stuff and I put it on not knowing exactly how it would work.
Let me tell you...it freakin works.
My spool time on the compounds was reduced noticably, my underhood temps dropped so much it's not even funny, my EGT's went down a bit at WOT....basically everything Levi can tell you is true.
I can drive the truck for hours....leave it running and hold my hand on the blanket on the exhaust housings and barely feel any heat coming through.
As far as performance goes....those blankets blow away any ceramic coating you can get...period.
Since every time I talk up a product I get the same old...."well..you got sponsored" BS let me say.....my blankets were in no way sponsored. I paid retail just like anyone else would.....and if I swapped turbos I'd buy more before I even installed them.
I even sent Pat a PM telling him about those things.
