Hey guys, I'm changing my headers tomorrow. The headers in my rex right now is stocked and I notice there is a heat shield there. I was wondering if it is okay to leave the heat shield off after I finish installing my new headers. I'm scared the engine might melt something. What do you guys think?

Got DCM 4-2-1 header and no shield and no melt on my b16.

Remove away amigo.
Your engine bay will not burn up.
That heat shield was to keep excess heat away from the radiator cooling fan.
Hope that helps to remove your worries.

i would recomend header wrap. I have had some on my header and d-pipe for a while now and it keeps the bay much cooler. good alternitave to a heat shield. ...and it keeps morons from burning there hands to bad...

I wished I had saved all the links. Here's one I Googled that gives the gist of the argument agains header wrapping. Now, they aren't against heat wraps. As I have heard others say, heat wraps are good for the components that you want to keep cool (A/C lines, fuel lines, air intakes). Use coatings for the parts you want to contain heat. HPC and JetHot being two of the top companies out there.

The coatings also look good IMO. If I even get my JRSC, I will be coating my header and downpipe.
Keep me posted! i'd love to know pricing n such... i'm thinking i'm going to coat them irregardless... cooler is ALWAYS better in the engine bay imho...

paid almost 200 extra to have our equal length subaru headers coated and then the coating fell off.

rusty header is a way of life for me, except for my blingity bling trust SS header i guess

Well, the DC header came coated. Then I sent it to JET to get recoated. (jet-hot.com IIRC), and heres the kicker...

according to cobb tuning, the place where we got our impreza header, they use HPC.

http://cobbtuning.com/impreza/powerpackage2.html#

"For pricing, we decided to make the system as accessible as possible. While we always want to do things full-tilt, we realize that may put some of our products out of reach of some enthusiasts. To combat that, we'll be offering the systems either HPC coated or uncoated and with or without a catalytic converter. The Uncoated systems will come pre-painted with high temperature paint to the outside of the pipe to minimize (read: not prevent) rusting. The Ceramic Coated systems are coated inside and out for rust protection and heat retention"

Charles asked me to jump on here and see if i can shed some light on the ceramic coatings questions.

First off, it would help me a great deal if you could tell me a little about your applications. Even better is if you could give me an idea of what EGT's you are running. We have different coatings for different temperature ranges.
I'm happy to answer any questions you have.

Thanks guys.

Shaun

ps. i'd give out my work #, but not sure if its cool with the Admins, so we'll just stick to this thread.
