Default Should i take the heat shealds off my header and up-pipe and wrap them in fiberglass?

Just wondering if i should take off the factory heat sheilds and wrap the pipes in fiberglass header tape or leave the stock sheilds on them. This is on my JDM tdo4 twin scroll setup also..

I haven't heard many, but there are horror stories out there that involve wrap + oil = fire. Everyone on here seems to be pro-wrap, but after reading a bit on corner-carvers.com, I'm staying far away from it. The chances of anything bad happening are very minimal, but I still won't risk it.
I guess you could wrap them, then wrap foil tightly around the heat wrap and seal it off somehow, that'd be pretty safe. Or you could get them coated and not have to worry at all.
Nice setup.
Edit: I guess the wrap and replacing the heat shields is pretty safe too, on the heavy side, but I wouldn't worry so much about a fire breaking out anymore.

Send them to Crucial Racing for ceramic coating/porting....then put the heat shields back on...

their standard WRX manifold extrude hone port & ceramic coating runs $200...probably be a little more w/ the twinscroll setup...definately worth it IMHO...

send them to CR for ceramic coating/porting, then wrap them, then put your HS's back on. talk about heat retention. (this is my plan in the future when i get the duckets).

LOL, good idea, but im not going to do it, thats alot of money i dont want to have invested... i dont need faster spool then 14.7 psi @ 2600 rpms... when i wraped the stock headers and installed an aftermarket cat-back that eliminated the second cat on my 1998 ej22 people thought i would get CEL codes for the oxygen sensors being to cold or some nonsence... I just wanted to make sure this wouldnt happen with the twin scroll setup installed.

if you don't send them in, i would wrap them and put the HS's back on like Ken said. And if anything, that will make it hotter when your 02 sensors are, not cooler.

If not an internal ceramic coating then wrap, seal with Thermotec, etc, and re-install heat shields.

Just wrap them and put the heat sheilds on, like said before. For the rest of you, the twin scroll headers are tube steel, they don't need to be extude honed like our crappy cast manifolds.

I am also scared of the wrap soaking up oil and starting a fire. I say wrap then put the heatshields back on, seems the safest most cost effective route.

If it were me I would coat them... Talk to Jeremy at Crucial tell him Dave aka. xr8ted sent you.. The turn around time isn't very long It is worth it in the long run you ever see the effects of what a wrapped pipe and a little water does?? Doesnt matter what kind of metal it is it speed up the corrosion process big time..
