I am about to install my dynomaxx long tubes. How important is is to do ceramic jet hot coating for heat and performance or is it just a looks thing? Being stainless I do they heat up more and do they discolor??

Tom

I'd do it to keep them looking great besides any other benifits!

The headers will discolor with heat. No need to have them coated, it won't make a difference in performance. Personally, I like the look just the way it is.
However, the tubes run directly under where the condensation drips from the hose. It sure does sizzle under there on a hot day. I don't think it is a problem.

I didn't have my Kooks done when I installed them on my 97...they did get bluish from the heat but nothing that looked terrible...I did put in a thicker heat treated tunnel plate though...this GREATLY reduced the heat coming up in the convection oven we call a console...I mean when stock after an hour cruise the change would burn your hand...after tunnel plate install...the console was nice and cool and I actually put things in there that were not heat sensitive! Like my Escort Radar detector! it would bake otherwise...

Where do I buy this tunnel plate?

Should decrease engine bay heat. On C4's it's nearly a must, things start melting and burning unless the're coated or wrapped.

this is the one I used...I used all the stock bolts as well...this really made the car nice and stiff, and its light weight to boot!

I think most skip it on stainless w/ no problems. We coated our LG Pro's cuz, well, why not? In for a penny, in for a pound. Also installed ceramic tunnel plate from EliteEngineering, KoolSox plug wire protectors. Overkill maybe but I instaled myself and figr'd I needed all the help/protection I could get.

According to JetHot's site, they run 300 degrees cooler as well as give you 3% better flow. 300 degrees is a significant amount, in my opinion.

I had mine done and I would do it again in a heartbeat. The fact that they don't discolor is just an added bonus.

How much did it cost and what was the turn around??

Thanks

Tom

Absolutely the truth.

I've done a few sets of headers using JET HOT ceramic metallic coating. They have quite a few colors available now. I can tell you there is a significant difference in the heat produced from the headers. They coat them inside and outside, which protects the metal...maybe stainless doesn't need it as much as mild steel, but they will look good for years. They also offer a terrific warranty. If the coating fails they'll remove it and refund your money. In all the headers I've had done, I never once needed that warranty. There is a specific break in procedure to follow or you can damage the finish...shouldn't be a problem unless you're breaking in a new untuned motor.

I think it's more of a look and heat thing. Me I did not have them coated and I wished i did.

So if I had been thinking I would do it for sure!

I have about 600 miles on mine and they look discolored quite a bit.

I would do it,.did it on my stainless headers......

It does help a lot with not contributing to underhood temps

They cool down MUCH quicker also,you can actually touch the tubes after a few short minutes....

And they look awfully nice

If you plan on keeping your vette for while, it is worth it.

How much did that all cost you?? and where did you get it done? Jet Hot.....????

It does look very nice!!!!

Thanks,

Tom

Can get an estimate from Jet Hot (http://www.jet-hot.com/pages/getestimate.php) or often the manufacturer of the headers w/ send them to get coated, get them back and send them to you. (thats what I had LG do).

If you ship em to Jet Hot yourself, I think it's around $300 to get the headers coated (plus shipping to and from Jet Hot)

it is well worth it

I bought mine coated .. granted their not SS .. but the difference between not and coated is night and day ..

if you enjoy heat in your car .. dont bother getting them coated.
