I've seen headers rust through within 5 years. Its worth it to get them coated.

 

mineaswell do it right the first time... since they are a PITA to install...

 

Please get them coated by Jet-Hot. You will be very happy you did it.

 

Looking back on it, I'm not so sure paying all the $ to get my Hookers Jet Hot coated were worth it.

After having them for 9 years now, they look the same as some of my freinds headers who didn't get theirs coated. Temperatures under the car seems to be just as hot as ones who weren't coated, and I seriously doubt they increase flow.

Perhaps I am alone here, but I doubt I will spend the $$$ it costs to have this done again.

 

Mine are coated pacesetter long tube headers. Only part that is even begining to rust is the bottom part of them. But that is just a couple little spots of it. Not even close to rusting through. But on the other hand i have seen uncoated headers start to rust all over just within a few months.

 

I know my manifolds would stay burning hot for an hour or two after I shut the car down, my coated headers I can literally grab with my hand after 15 minutes or so after shutting the car down.

It must be nice for the track and stuff where you need to work on the car in between passes and stuff like that.

That being said, the coating on my pacesetters BLOWS, I've had them about 6 months(although 6 months of winter, some snow and salt) the bottoms look like **** and the tops ain't THAT great, but they still look alright. I think I am gonna go scotchbrite them with soap and water and see if I can get em to look alright. If your gonna get em coated, get em coated by an aftermarket company in your area that specializes in coatings of this nature.

 

The stock manifolds are a LOT thicker than headers, and therefore will retain heat longer. This is not a good comparison.

Having seen the difference between non coated vs. coated, I keep seeing little to NO difference except for appearance wise, or if the headers are made from a cheep metal then they do seem to corode faster. I personally buy headers that are not the cheep ones and are made from a better quality metal.

 

I DEFINATLY recommend coating headers, expecially if they are not stainless steel. The coating prevent's rust, reduces underhood temps, and looks great. Plus it has a lifetime warranty!

We sell some Jet Hot Coated Pacesetters that are an awesome value considering that you get a life time warranty on the headers with the coating-

No offense MarylandSpeed, but as stated in the beginning of my thread, I am looking for opinions from people not biased or who would not make a profit here. Its kind of like calling different Radar detector companies and asking them which one is the best. They all will say the same thing "our Radar detector is the best".

 

I just re-read the thread and I voted no its not worth the temp differences/flow gains. I think that reasoning is BS, when the cars moving all the heat from the headers is being blown out the back(sort of like a fan), so the temp differences I would imagine are BS right there, and increasing the flow, I can't see how a coating would increase the flow by any measurable gains.

Just my opinions more or less, I don't claim any of this to be fact.

However, I do believe its worth the looks, and want to believe it helps increase the life of the headers(by slowing down rust).

 

Ive had my uncoated mac headers on my car for about a year now. The only parts rusting on my headers are the parts that were scratched during installation or scratched in some way.Other then that they look pretty good and plus I saved like over 200 dollers.

 

Thats just it, they'll still rust from the inside out. Plus the higher heat retained on the inside from the coating also increases oxidation.

Like I said before. My uncoated MAC's look better than some coated headers of the same age, both on daily driven cars.
