Who has them with the Jet hot? What are your thoughts about them. I currently have the Jet hot long tubes but the coating is coming off and there is some rust on them also. This is after 2k miles .They are about 4 years old, so I can't send them back for recoating, but I figure why anyhow? They will just rust thru again.
I don't care that they are pricey. No rust is worth it for me. I want the thermal coating to keep the heat down . Just want to know who has them.

 

I contemplated getting my Kooks coated, but I figured, "why". Plus
when I called the Kooks tech folks, they said to not get them coated
until you verify fitment. So, I'm gonna fit the headers and then take
them off, send them off to get coated, wait, then re-bolt them back up?

I paid for top-quality stainless headers - I figure I dont need the coating.

 

Heat is my main issue. Rust 2nd.

 

I had mine coated with Jet Hot's Extreme Sterling. They looked nice, and the coating appeared to be of very good quality. The Extreme Sterling isn't as shiny as the regular sterling, but offers better protection & insulation at higher temps. I haven't driven my car since I installed the headers, so I can't really attest to the durability. The primary reasons I had them coated was to keeps temps down, to keep them looking nice, and the supposed performance benefits. I recently read something where some company claimed a 7 rwhp difference between coated and uncoated Pacesetters.

 

I am sure the heat that is retained inside the pipes increases the velocity of the gases escaping

 

That's correct. I can't wait to drive the damn thing. I haven't driven it since October of 2000.

 

Why so long?

 

The catalytic converter collapsed one day during rush hour in Atlanta. I had it "replaced", which didn't help. I bought a Grand Cherokee, hauled my Z to Kentucky and put it in my dad's garage where it sat for close to 7 years. It's running great now, but my car is in Ky and I'm in Michigan.

 

you dont have to worry about rust on kooks headers, they are stainless steel

 

Ok, I'm not that smart so I'm going to ask a dumb question, and hopefully not threadjack... what is the benefit from cooler (coated) headers?

I presume its to cut down on engine bay heat, but how much does the coating really help? Do long tubes get hotter than the stock manifolds?

I'm guessing that the coating causes the headers to radiate less heat, but that heat has to go somewhere.. down the exhaust pipes I presume? Does this give a performance benefit? I guess it might heat up your cats quicker, or make them hotter, but that probably wouldn't be a performance gain...

I'm saving my money for some Kooks headers as well since I like the idea of stainless, and I have also wondered why people would pay the extra money for the coating. Does it really matter if the engine compartment gets a little hotter?

 

The engine bays in these cars is cramped and they do get hot.
The coating does keep the heat inside the pipes, which should, at least, maintain the velocity of the gases exiting thru the exhaust. The other thing I didn't like much about my long tubes was how close they are to fuel lines, so the coating was a little more reassuring.
Iam a little hesitant to do the jet hot only because the coating came off fairly quick. I don't drive my car in the rain, it has never seen snow( since I bought in in 01'). They only had 2000 miles on them since being installed, NEW. Maybe they got hot enough to begin baking the stuff off oo them

 

Is there any chance that rust may have contributed to the coating coming off so soon? At least with stainless headers, if & when the coating begins to come off, you don't have to worry about rust.

I did check out a local car when I was trying to decide what type of exhaust I wanted. He had coated Kooks, and I'm pretty sure the coating was Jet Hot Sterling. I believe they had been on his car for over a year, and they still looked brand new.

Anyone know how hot the exhaust gases get on a pretty much stock setup? I believe Jet Hots Extreme Sterling is supposed to be good up to 1700 degrees. I believe their regular Sterling is good up to 1300.

 

Get a cowl induction hood

 

The headers were brand new . I still don't quite understand on how they can coat the entire inside and know for sure it is coated, but whatever....
My car always ran rich so I can't tell what tthe coating looks like inside. I'll post some pics of the Jet hots in a bit.....

Give $800 and I'll be glad to do so.
