Exhaust header wrap on the downpipe?

The heat wrap does do a great job but make sure you dont wrap mild steel as it will trap the moisture and rust out your DP. Ceramic coating is great too just more costly. Exhaust piping should be stainless anyway as it tends to hold in the heat better than mild steel anyway and is less prone to cracking.OneJoeZee said:
I've got mine wrapped with DEI heat wrap, Header, turbo blanket, downpipe. It's really not bad at all under my hood.

Thanks for the info.
In my case, maybe it's because the downpipe is not one solid tube. Since I have twins, I have two and they have to "Y" up at a point and also have a "Y" where the wastegates are routed back in... so those areas aren't wrapped completely like the rest. The wrap job just may not be sufficient to make a significant different too. I'm not sure.
I may just be feeling alot of the heat off the turbines though... Those are right in my face and not coated or wrapped with anything.
I have a DPP, I put the stock heat sheild back on (slightly modified) and it helps a lot...
I've heard of ceramic couting AND wrapping, but I'm against wrapping in most cases as it will trap the heat to the point where it can crack things...

ive heard nothing but good things about exhaust wrap even when talking to 4th gen guys. so ill probably join the club too!

Exactly. If done correctly your engine bay temp will drop, your intake air temp will drop, and your cooalnt temp should also drop.
Joe - The heatwrap will only make the most difference on the exhaust pipes. Obivously on turbo cars that includes the manifold, rear of the turbo, and the downpipe. If your manifold is cast it will be tough to wrap, I did not do mine and only would if it was a tubular manifold where the wrap could be used correctly. If you feel your setup is still too hot even with heatwrap on the downpipes, you could try finding 2 turbo blankets that fit, but honestly I wouldn't waste my time unless I could wrap the whole exhaust manifold also. A hood vent would also help your situation, if you were willing to put one in your hood.

...and I notice top fuel dragsters and funny cars run the "wrap" and I would think $'s would be no obstacle to those guys.
Wrap works on the outside surface. Coatings are applied to both the inside & outside surfaces, which reduces thermal fatigue to the metal several magnitudes. Corrosion protection is another significant benefit. So there is more to coatings than mere thermal reduction. I use both wrap & coatings when possible [EG, DP, but not the turbo].gixxer750 said:
someone that agrees with me... seen header wrap do bad things to whatever it was wrapped around.
ceramic coating the header and then wrapping it does a hell of a lot, and it won't have the same issues as just wrap...

i found a spot in washington that does powder coating and ceramic coating CHEAP! He did some ceramic coating for my buddies eclipse, and it turned out well. he has a 20 foot oven, so you can coat just about anything. heck, maybe ill coat my whole car. the best part is his prices. for a downpipe, he wire-wheeled the whole thing, and then 2000 degree ceramic coated it for $30-$40. Here is the shops info.

They also have double wall headers not really a valid comparison.suprabad said:
I have the Header, Turbine Housing and Dump pipe coated and run a Blankie on the Turbine as being RHD all of my brake stuff is on that side.
I've had mine hot enough to melt the Techline coating on the T3/T4 adaptor but it's still holing on.
If I shut my motor down in a minute or so I can touch the header without burning myself but can't touch a Cam Cover.

yes, it was a dp off of a dsm, but as far as we could see inside the dp, he had coated it. my buddy had to take some steel wool to outside to buff out the ceramic coating, as it came back with a surface that was not completely smooth. not a big deal, but i figure its worth noteing.
