i'd like to know this as well--

i've HEARD that wraping your header can cause the heat to crack the pipe, but then why would it work for other cars and not ours??

You shouldn't wrap your stock header--it should be an aftermarket header without the cats. Not all cars have cats in their headers, but the header should be SS with no cats. Some turbo companies wrap their downpipes, I think Toyomoto does this (but I'm not positive).

if it's stock...you call it an exhaust manifold...not a header...just an FYI...

I wrapped my downpipe with heat wrap because its like 1/8" away from a coolant hose. The coolant hose is happy and cool - and you can touch the heatwrap.

Its good stuff however not aesthetically pleasing - if you plan on popping your hood alot you should get a heat shield.
