Remove O2 sensor.
Remove the old manifold.
Put the new one on.
Re install O2 sensor.

Done :)

Use PB Blaster 2 days, then 1 day, a few hours, and then during the operation

Not sure on the torque but pretty tight. A new gasket should also be used however if the old one is good then id just use that again.

PB Blaster....Go to Autozone and ask them where it is. It makes WD 40 look like water.

sick, it came with a new gasket so ima just use that. but wut are the name of the bolts that hold the manifold to the engine? ill just look em up and replace those too. (dont wanna stick those rusty pieces into a brand new part)

and do u think i could just do this at home without taking the engine out or anything? cuz i dont wanna bring it to the shop if i dont have to

I suggest you get the service manual and read it. Seems like you have alot of questions for what should be a simple operation.

haha Keep asking the questions. Thats what this forum is here for. I was merely suggesting that a service manual would be best so that you dont have to keep getting online to ask questions. Bad phrase of wording on my part.

Yes its ok to drive after a few minutes. I suggest spraying it at night so that it has time to sit and do its magic.

well i replaced it! it looks amazing!!
i had to custom weld part of the exhaust part to fit it. it took all day and i bought the manual (didnt do much) but i finally got it done. the engine just sounds wierd now though.. :/
(just a guess) but i think the old manifold had a silencer on it, cuz there was a huge round pipe right on the manifold that wasnt on the new one. it makes a loud rattle now when i accelerate. even the slightest bit, but not when its at idle... i checked everything like 3 or 4 times and there's no loose parts i could find... think its just the new part??

The header doest have a pre-cat, its just straight pipe so its def going to sound different. However the rattle....Not to sure.

ok, so i clipped a wire on the seconary intake... :/
i noticed alot of people have theirs removed in car pictures, u know wut exactly it does? and would i really want to remove it or not?

No one has it removed. What year car is yours? The '99b started coming with secondary air pumps for emissions purposes. years before that didnt have it. If you cut the wire to it, fix it and reset the code. Hopefully that will keep it off.

woops, nevermind. its the preheater. when i put the new gasket on undeneath the new header, the gasket covers the hose for the preheater, wich is why my lights going off :/
not the stupid wire...
other than drilling a hole through the new gasket, is there any other way of getting that light off??

RC1488

I dont think so. The PCM looks for a change in the 02 sensor, and if it doesnt see the change it wants, it thinks the air pump is busted.

so im gonna have to take it off and drill that hole?

RC1488

If the gasket is covering the hole for the pump , then i would think yes. I cant think of any way around it. Only other option is to guess where the hole is and drill a small pilot hole, then increase bit size untill you have the hole made. Doing this leaving the gasket on.
