Hey Guys,

Wondering what you guys thought about exhaust wrap. I was thinking of wraping my ets tubular manifold to keep the heat in the manifold...
Any thoughts or suggestions would be great.

This is the wrap I was looking into to...

DEI titanium wrap

• Withstands 1800˚F direct/2500˚F intermittent heat
• Promotes increased flow for improved performance
• Reduces temperature & vibration breakdown
• Extremely pliable for a tight and secure wrap
• DEI HT Silicone Coating not required
• Pre-wetting roll not necessary for wrapping
• Hi-tech carbon fiber look
• High resistance to abrasions, oil spills, temperatures and vibration breakdown

Thanks again,

I prefer high temp coating to wrapping the header. You might want to look into that instead. There are quite a few color options and companies out there that offer high temp coatings. I had a local shop do mine.

 

Thanks for the suggestion. The main reason why I dropped the coatimg idea is because eventually it chips or flakes off... When i got my mani from ets, the steered me away from it even though that offer it. So then i was going to ceramic coat it but that too chips... Sigh... So its nothing or wrap at this point...

 

i wrapped my stock header with the dei titanium stuff
when bonnet is opened, i get less heat blast from it

 

+1 to this ^

... Not that I can say you will have a problem for sure, but I wrapped my manifold on my SR20 setup and cracked the manifold a couple of times. I replaced the manifold and wrapped it again, and had the same problem. This was running a cast iron log-style manifold, and my EGTs weren't crazy. My only guess was that the heat was being too isolated. Dunno if that is the case, but just some food for thought. On the other hand, I've never heard of this being a problem with coated manifolds (provided you have a good tune and aren't getting outrageous EGTs).

 

^^ Great info and feedback, I will definently have to do more research on cracked manifolds due to wrapping them... I dont want any issues but definently want to control exterior exhaust heat as much as possible.. Too many small grey areas when doing a build

 

I used the DEI Titanium wrap and also then wrapped it with aluminum tape and secured it with thin wire. This way the wrap doesnīt degrade or get worn with all the work that usually goes on around that area, also less chances of a fire if the is an oil spill or something. Itīs been this way for over a year.

Cheers,

Ricardo

 

I've ran mine for a few years now without wrapping..everyone keeps telling me to wrap the stupid thing..never had any issues honestly.. but now that its off the car again I'm gonna just ceramic coat all the hot parts including the hotside of the turbo... better to just leave it how it is or spend the extra to ceramic coat the sucker.. wrap IMHO is waste of time and money unless your wrapping say the downpipe..something that doesn't have many if any bends..wrapping a tubular manifold has PITA written all over it

also as side note.. I had my stock turbo on a tubular manifold that I had ceramic coated.. never an issue with "chipping" and to this day its still on another evo without any issues last I checked..thats going on nearly 8yrs now.. the whole "chipping" issue with ceramic coating is related to if you hit it with something repeatedly..as long as your not taking it off and on a million times or dropping **** on it..it really doesn't do anything bad

 

I just wrapped mine this weekend...I heat coated it as well but decided to go with a wrap on top bc I have an OLD SCHOOL Journal turbo and want to try and help spoil(also help heat in the engine bay)..there are a few things you should know about heat treating and thats if you do it yourself with high temp jet coat spray can...you cant just just spray a couple coats on but it has to be baked as well...as far as the titanium wrap...it didnt sell me to well...i pre soaked it to make sure I get a tight wrap and the material falls apart easy!I will post up pics later when i am out of work

 

On another note...I have used DEI's regular wrap and silicone spray on my downpipes and they head for 3-4 years before it started to deteriorate the wrap

 

i ran my ebay manifold with heat wrap for a few years without issue. when i took it off to sell there was markings left from the wrap but no cracks. my car was driven in every westher possible. i think the readon i had no cracks was because i didnt wrap it as tight as most people and i left the welds uncovered.

now i have a manifold with just some hi temp rustoleum that has chipped away due to wrenches hitting it. next time its off i will get it swain tech coated.

 

May I ask where you got that Aluminium tape?

 

Any big hardware store should have the aluminum tape, itīs used for house/building airconditioning stuff. Suretape is a brand I could get here in Peru. One thing though, after installing and running the car, youīll get a lot of smoke from the addesive burning off, and after some wot driving then itīs gone for good.

 

That tape is not rated for the 600-1200 F the exhaust will be running.

Your just asking for a underhood fire...

 

I also pref coating than wrap. Have you look Jet-hot coating? I had them coating manifold on 350z and it looked brand new till the day i sold.
