It will prevent the starter solenoid from melting. I wrapped mine with the DEI titanium wrap after having a no start problem, charging issues etc. all due to a melted solenoid where the battery cable meets the alternator positive wire at the starter solenoid.

I agree. Called the LG Motorsports guys and they did not recommend. They made a very good point ... coated or uncoated, quality 304 SS headers will dissipate heat exponentially faster than the OEM cast iron exhaust manifolds. After having mine on for 72 hours, I wholeheartedly agree. Bank the 200 clams for Mother's Day.

It's the reason I went 304 stainless this time around. As far as aesthetics go, that's subjective, as I myself prefer the look of 304 stainless over the Jet-Hot coating. A Jet-Hot coated set of $500 headers looks the same as a Jet-Hot coated 304 SS set.409 SS, that's a different story, but 304 SS gets to be a nice golden color :-)

Possible yes. But if you haven't had issues, why spend the money?

i wish i had the two links about this
found them on the web
was awesome reading with some factual information
they both kindda said the same thing with stainless
don't coat it
you can loose performance
ok..... well lets face it your not gonna loose say 50% power
these articales were mainly from race teams and they found you loose power due to the heat transfer and slowing of the exhaust gasses
it was like 10hp on one of the cars, but again it was a very high HP car
so to me would you feel that 10hp... probably not
on a dyno yes
regular headers were totally different
and i dont know if Ti has the same issues or not
in speaking with someone from Shafiroff a few years ago, they also dont recommend coating stainless, i'd take their word for sure
i myself don't like coating stainless, but thats just me
if your goal is a good show car, do what makes you happy
if you are trying for EVERY single .25hp you can squeeze... i'd leave stainless uncoated
but... who knows, your results can vary

How many headers come with heat shields besides the OEM ones? Or turbo manifolds
The coating will act like a heat shield that is no longer present. It will help keep damaging heat away from fragile components which will fail from the heat radiating off the headers over time. It's just a matter of time.
It took less than a year of running my Kooks un coated for the starter solenoid to fail. (visually it was fine, nothing was loose etc...but the car was having charging problems as well as a dreaded no start problem due to the contacts slightly separating inside the solenoid and arcing was occurring)

I have had uncoated headers with zero troubles for 6 years now. My friend had coated headers and after about 5 years his coating flaked off and they looked terrible.
Both worked fine. It's possible he got a bad coat job?
In my 10 years on the forum the only compelling reason to have them coated that I can recall is looks. Since I don't have a show car, and I tend to keep my cars a long time, I never bothered.
