Our biggest issue with our car is? You guessed it...Heat!!!

After watching a few videos on ceramic coating headers I am blown away at how much heat they reduce.
​​​​​​i was on the fence on doing it but after seeing a few videos showing 500 degree temp difference just from coating I am sold.

To put into perspective..mi did 6 back to back 1/4 mile runs and my oil hit 248 in 70 degree weather and today being 90 out I babied the car and was crusing at 242-246 barely going past 4k rpms.

I opened the hood and I couldn't believe how much heat was coming out the exhaust area.

I will be back to report on the ceramic coating as I'm talking to a few local places to do it but after seeing 500-600 degree temp drops I'm surprised this isn't more talked about.

Mine are not coated mbh. I have not seen an increase in under hood temps with headers. As far as reduction with coating them no idea.

Did you notice a big difference in under hood temps?

I was not saying there is an increase with running headers just a huge decrease when ceramic coating any headers or even stock exhaust system.

I will look for the video that convinced me to coat mine before installing.

Basically was like a 500 degree difference in temps pointing a Lazer gun at them.

That blocked heat should reduce the engine bay and oil temps etc.

Don't have any true data, but under hood temps seem about the same or slightly less than before install. Within 15-20 after shut down I've worked underneath, can touch them quickly without getting burnt.

Here is a good video from 4 min mark they test ceramic. 185 deg vs 870 deg

I wonder what the real world improvement in under hood temps is though.

I'll bet a nicely crafted heat shield will probably do just as good a job

Is there any quantitative improvement for oil temps? Anyone have a comparison?

I really want headers but theyre just so dam expensive. The headers are over $4000 CAD to ship a new set, and with installation and taxes, it'll be over 5k. But if it can keep my engine running cooler so I wont need the 44o upgrade for track, then its a good investment IMO.

I actually just thought about this some more and wouldn't headers runnkng higher temps lower the engine temp? If the stainless steel tubes can can heat up, and the tubes will be under the car, then doesn't that dissipate more heat? Versus ceramic coated tubes which do not absorb as much heat, therefore leaving more heat in the engine.

hope I worded it clearly enough. All that heat in our engines has to go somewhere. If regular header tubes don't heat up as much, then more of the heat stays in the engine methinks.
