I wouldnt do it. When I ran a turbo on my Subaru RS, I had the whole exhaust manifold, turbo, downpipe untilt the cat jet-hot coated. The stuff barely lasted a winter in PA before multiple rust spots were seen. I didnt bother sending it back for the guarantee work because it took them about a month to send it back the first time around. It really was a pain in the butt to deal with.

Just my crappy experience. I'm sure if your cars never see snow or lots of gravel the outcome may be very different.

You'd never believe who gave me the above advice.

 

I was going to get a spoon or mugen header and do it to that and the piping up to the cat.

I heard it dropped under hood temperatures and also kept exhaust velocity up, helping with scavenging.

Not true?

RWD_RCKT,

Did you coat inside and out, or just outside?

 

My header is coated inside and out. The only way to do it.

 

I was going to have my Mugen done. Now I am having second thoughts with all the scepticism.

 

i'm looking to get this done... which jet hot coating would be best for an NA application? extreme sterling? or jet-hot 2000?

 

Extreme Sterling would be the one I would get if you want to pay a bit extra. Jet Hot 2000 would not do as well on NA.

 

swain tech and hpc also do coatings, i really liked swain techs white coating, i have my exhaust housing and manifold in hpc flat black 2400 coat, goes on te car next month, ill let u guys know how it holds up
