I just recently got headers and was thinking about using a thermal wrap. My neighbor told me that it wasn't a good idea for daily driving, they would eventually crack! My neighbor is also a delusional drunk that beats his wife! (true story) Is this the alcohol doing the talking? Or is it true?

 

It's a header not headers. Stay away for the wrap.

 

if you have cheap headers I wouldn't do it. If you paid good money for them you will prolly be alright. When you put the wrap on soak it in water for a while then wrap it while'st it's wet. When the header heats up it will shrink and provide a really tight fit.

 

Rippin idea man!!! Lower engine bay temps is the way to go!! Do it and let me know!! Ive been waiting o buy a carb legal header ( Yay for California!! ) and a I was going to do the same thing.

 

Its a dc "header" and its in good condition, their isnt any rust or dents. Im gon try it and if it cracks F@CK IT!

 

Yeah!!! Thats the spirit!!! Let me know cuz I wanna do it!!

 

heard the wrap is a horrible idea....

 

Yeah...but has anyone learned from experience? Until someone gives me advice from actually doing it themselves, those type of comments don't help. Definitely appreciate the feedback tho. I'm going to update when they're on with posted picks.

 

think i read something in the civic forums about it..

edit: heres the post. read it before wrapping anything... hope it helps

Wrapping a mild steel header with thin walled tubing and weak welds will greatly increase the risk of cracking for relatively little reward.

Also, for those of you who have to follow CA smog laws, header wrap is a de jure illegal modification.
Header wrap isn't an OEM equivalent part and no header wrap is sold with a CARB Exemption Order #.

Frankly I wouldn't bother in either case.
