anyone know??

 

I dont think its illegal, but if have a CARB legal header (such as a DC, Greddy etc) then you are going to want to leave the CARB label/plaque showing.

 

why would you want to on a street car anyway... all it will do is promote rusting

he has a point. if you are worried about heat, get a heatshield. only place i have ever used heatwrap is on my bike where my exhaust would normally burn my leg.

 

to tell you the truth wrap it if you want .. it well help keep the engine bay cooler.. dont listen to these guys .... and there is no reason for it to be illegal..

 

and who cares about the engine looking pretty as long as your engine is happier?

at the cost of your header...

Get a stainless header and u will have no rust/corrosion issues. If u get like a mild steel header..then u may run into problems with corroding and possibly cracking. I have NO personal experience with the stuff, but i spoke with a guy who did and he just said stick with stainless if u want to use the wrap.

 

why would anyone not want stainless or ceramic coating...

somewhat misleading - as stainless pipes can have problems from heat wrap... such as corrosion - even if it doesnt rain and you live in someplace like say, vegas and drive thru the desert a lot - the sand can get in there and just rub and rub and rub - kinda like sandpaper

 

I think that fourthgenhatchB17's first comment sums it up;

If it's a legal manifold, wrapping it would cover the CARB number. As a result, it could be possible for a cop to send you to a referee to verify it. The Referee would then require you to remove the wrap to view the tag.

All in all a major pain in the rear just to prove it's legal, but I could see it playing out that way.

I guess thats true. I, however have an old school DC stainless header that had been wrapped by the previous owner. The wrap has since been removed but there is absolutely NO corrosion. The shine of the SS is long gone and the new color is like a dull bronze (actually looks cool ). So with my SS header that has been previously wrapped, there is no corrosion.

BTW, Wes V i will be heading to get my car BAR'ed very soon. I went to rio hondo college and spoke with the REF already. He was pretty cool.

 

thanks for the input....actually, i kind of think heat wrap, if done right, looks kind of sexy also....plus I don't show my car right now, and rarely see the engine.....

I like the look of it plus it keeps things cooler and has some performance bonuses.......so if I am careful to not cover the plate on my Greddy header.......and stay semi away from welds....then I say why not...that is if I can find some fairly easy.......

I also plan to, on the parts of the exhaust that bolt up, put a little jb weld on the parts of the flanges that come together....just enough to keep exhaust from escaping but not enough to not be able to break it if need be.......may be stupid, but it makes sense to me, even if it only is a street car, plus it gives me something to do........

and also about the heat wrap, I have to replace my entire exhaust except the header, which would make it way easier to wrap while the exhaust is off....

and besides....all exhausts are going to rust given the time....

oh yea, and because we live in the *desert* doesn't mean we drive ON the actual sand......we haven't converted our civics to dune buggies just yet.....

 

If anything, wrapping the header will decrease cold-start emissions. When it comes to fast catalytic converter light-off, a wrapped header is better than an unwrapped one because the exhaust looses less heat to the environment. Also, cat light-off would be quicker with a wrapped header than a stock cast manifold due to decreased thermal mass. So from an emissions standpoint, a wrapped header is as good as you can get.

 

header wrap is only illegal when you have it on a carb approved header. why? it voids the warranty and/or the carb sticker,plate, paper whatever. it says so on the instructions included on my dc header.

Wrapping a header DOES void the warranty. But I have never heard of it voiding the CARB approval.

 

knowing cali well.. cops will say something about your headers being heat wrap... "you have turbo in there ...dont you"

 

header wrap will not disqualify the CARB status of your header. just dont cover the plaque, as suggested. not a big deal, its only 1 inch from the flange. ive tested my wrapped header twice in california and have had no issue.

you can decide whether you want to wrap your header or not based on the warranty condition that wrapping voids the warranty. but from my personal and every header ive personally seen, both mild steel with ceramic coating and stainless steel versions, there have been no longterm drawback from wrapping. no extra corrosion, no pitting, no cracks.

ive also seen normally used headers crack on their own, without header wrap or anything. so i figure any issues of cracks and whatnot are simply a matter of build quality. once made, welds are hard to examine thoroughly (especially from the inside) so its hard to totally assure quality except making sure its been done right, which only the builder and how much he cares about his (companies) reputation matter.

but to answer the question, its not a problem to pass CARB.
