header install
took it upon myself to install a cheap ebay header since my oem header was about to fall apart..
before

heat shield removed revealing the crack, and a roasted wasp i think..

header removed, that is p.b blaster on the ground btw in case your wondering..

-edit: after driving 80 miles

all in all i think it took me about 2 hrs and 30 mins, and this is basically my first time turning a wrench on a car..
fired it up, no leaks, took it for a wot run and dont feel much difference up top, but i definitly feel a difference in the mid range.
so i am now catless, using the weapon R CEL eliminator, and so far its working fine.
so we'll see how long this cheapo header lasts, if it cracks anytime soon i guess ill just do a ex exhaust conversion since im now confident in my ability to do it myself.

Re: header install
Take your time, lots of thin coats with some time inbetween.. high temp spray paint. You might want to scuff it down with some fine sandpaper too so the paint sticks... high temp primer might even be a good idea too if you can find it.

Re: header install
Yours will because you've eliminated the catalytic converter. Ways around that is to do the spark plug non-fouler thing or convert to an ex exhaust setup.
edit: just read you're using a CEL eliminator.. disregard my post.. What code is it throwing?

That's the defouler. It basically backs up the o2 sensor so it does not detect as much gases after the cat has been eliminated. Turning off your check engine light which comes on due to the o2 sensor.

Re: header install
with your car you can't use the defouler trivk because its to long and will hit your alternater you need to get a Angled mechanical simulater megan racing makes one for 25 bucks.

Re: header install
the weapon R CEL eliminator fit on my car just fine, just make sure you put it on the header before you put the header on the car. 300+ miles with it so far and no CEL ( my commute is 80 miles a day ;o )
Re: header install
The reason why you have to get a defouler for an after market header is because the cat if it still has one is not like the oem cat. If you look into a cat all it is is a big honeycomb and where the secondary sensor is it is basically surronded by a big wall. When you take it out of that wall it will sense all of those gases just like the primary sensor which causes the check engine which is usually called o2 sensor below the threshold. When you put it in the defouler it acts just like that cat with the wall.
But a ebay header is a great replacement for a header if it cracks or anything. It is cheap rather than the oem cat which is expensive.

Re: header install

Re: header install

a newb question in know....

Re: header install
you won't have any problem with throwing cel code's cuz you car is an ex, different exhaust setup. Just make sure when you search it on ebay the header your looking for is to fit an ex, not a dx or lx.

Did you torque it down to the proper specs? If you overtightened the nuts it will be a nightmare to remove
