Off of this topic but one of my stud to the header is broken off with the nut and only a little piece left to it, can barely bolt a nut on it. It's the one on the header to the driver side bottom. Is it hard to replace it? any suggestions?

ok i change the headers to day and man what bitch the only hard thing was. was the last bolt on the far left hidding behind the alternator. but hey its on. the one problem is my check engine light went on when i gunned it full thortle and now its stuck on. did anyone have this problem???

I didn't and i'm sure mostly everyone else didn't. You may have a leak. Check all the bolts to make sure they're torqued enough.

did anyones check engine light go one once after they installed it??? mine did i think it because of the bottom o2 sensor. so i reset the ecu and now the light only goes on when i floor it. is this because of the o2 sensor???

Probably... most likely... OBD2... Yes. Go get the code read...


Extract that stud and replace it with a new one. A pair of vice grips should extract them OK... but stud extractors are best if you got em.

use the anti-fouler trick for the o2 sensor

Mine came on about 3-4 months after the install. I have an actron code reader and the code it was throwing had to do with the cat malfunctioning. Obviously there is no cat so I guess the car is correct in stating its not working. Couple of weeks ago the light came on again, same code, same problem.

It will most likely happen to everyone that has done the header. I however think that your CEL light is going to be caused by something else...

what trick are you talking about??? or should i replace the bottom o2 sensor

after i change the headers the check engine light wasnt not untill i pass 4k rpm. then it stays on. once i reset the ecu the light goes off and stays off untill i go pass 4k rpm again why is this???

maybe the engine its telling you not to treat her so bad, be smooth ....lol

i did the headers on my st with ebay bought ones. now for the first o2 sensor i justed plugged it with a piece of steel and 2 bolts. check engine light didnt come on.

idkn thats pretty hard for me to do. i got the need for speed lol

FINALLY got mine installed! Sounds sweet! too bad its already gold but oh well.. I thought about Heat Wrapping it but I just don't have the money to do it...

If you look on ebay, you can find DEI exhaust wraps for like 30 or so. Also, lets hope you don't start melting a bit of the plastic off your alternator or dipstick---i've already seen it happen.

That would be no bueno! Is it possible to wrap it while its on? I just don't wanna take it off. .

haha you could try, but i wouldn't count on how good of a job you'll manage...probably could with the more open space now since you took off your stock headers and all. Oh and make sure you get yourself some steel zipties to hold the wrapping.

Lol well I think I may try it that way ha ha! If it doesn't work, no harm done right? I'll just have to take it off and do it. . Even tho I REALLY don't want to do that

well here's a pic of my headers before installing them and even this...is not considered the best job and as a matter of fact, quite sloppily done but w/e as long as it holds on well, but I wrapped pretty much the main areas that heat up mostly. I can't remember how long this one was but I ran out.

Yes, i couldn't find my pair of shears to cut the excess remainder of the steel ziptie.
