Heat Shield

hey everyone,
Im looking to keep my lower intake manifold cool from the heat off my header. I have a Rb header brand new thats been installed for a couple of months, its not wrapped and I have no heat shields on the whole exhaust system (bonez cat, rb y-pipe and mufflers).

I know that I've seen some great examples of heat shields on the forum here before, but I can't seem to find any. If anyone wants to post their setup that would be awesome!

Also, I was looking into just getting a good heat wrap for the headers but after reading some negative feedback about them collecting moisture and possibly rusting and reducing the life of the header. IDK. can someone back this up or disagree with this statement?

I wana see some heat shields! Thanks!

i don't see why the stock exhaust manifold heat shield couldn't be used with the RB header.

in order to use the stock heat shield with headers you would have to fabricate something to secure it in place, because it originally bolted the the stock exhaust manifold

this is true, it was originally bolted to the exhaust manifold. Im sure I could use some elbow brackets from ace. Any other ideas?

They work with Inconel steel stuff quite a bit, and may be able to build you something. While it won't be cheap, it will certainly do the job well.

I wrapped my RB header when I first got it. It was cheap, easily available, and took no time to wrap. And no, I don't want to hear why it may be bad, ect, ect...

All the cons about the header life degrading, yes the wrap will hold moisture, but if your driving, trust me, it will evaporate and the wrap will be dry in no time. Have had it wrapped for about 2 years, the header still looks almost like new.

^I may be talking out of my ***, but isn't part of the problem with wrapping exhaust that if it's not also treated on the inside that the metal degrades from the inside out?

IIRC that is what I read about turbo manifolds and exhaust.

This stuff looks very nice, a bit expensive but the quality is definitely there. Thanks!

Good, I'm glad you have had great experience with the wrap over the years. This is what I originally wanted to do but was a little turned off about the moisture myth. Do you remember what wrap it is that you used or where you got it?

One more thing, have you ever taken the wrap off within the two years of having it to see for yourself if it's holding up?

I have peeked through the wrap and it looked in good condition.

thats good. After some further research on the topic, i found a thread where people are talking about coating their lim and uim with that ceramic or whatever. Such a good idea to do this. I don't think I have the patients or the money to have this done though, atleast yet.

I really like that inconel steel stuff from turblown. Do you think I can use that 12x12 sheet and just rig it somewhere to reflect the heat away from the lim and my acv/actuators. It looks like a blanket thats flexible so it seems perfect.

Thanks for the help guys, but i still want to seem some engine bays that are using shields for an example.

12 x 12 sheet should work for you, you can mold the stuff.

It can touch the header, its good to 2600 deg F. However it would be best to leave at least a 1/4" air gap for maximum heat shielding.

right on, I was only asking because it is a very tight squeeze above the header, but if it can touch the header than I should have no problem. Just have to figure out a way to mount it I guess. Thanks
