I will be doing full exhaust on my car and need to know where all the sensor are. I will be getting the ssautochrome 4-2-1 header.. are there any other sensors besides the 2 that will go on the header? I am also planning on getting a high-flow cat and the mbrp cat-back.

Does anyone have this setup? and if so, how ya like it? Thanks.

 

You will have an O2 sensor after the cat too....and depending on which gen you have you might only have one to plug into the header. I only have one on mine.

 

I have a 2nd gen. Does that mean I have 2 or 3 sensors?

 

Both Gens have 2 O2 Sensors
I think the SS autochrome one has 2 bungs already made for the O2s, you may need to extend the wires of the rear O2 sensor. Not sure about the SS one, but the SR one you did.

And no, no other sensors, just 2 O2s

 

Don't know what kayJai said up there, but that's the setup I have man, those headers and the MBRP. Unfortunately it's not installed yet.

Yet.

BTW, what do I need to install this? I've got both setups, what gaskets do I need? How long will it take?

 

it didnt come with gaskets?

you might want to replace the header gasket and it should of came with gaskets for the connections of the pipes down the line.

 

if there are only 2 O2 sensors, why does the CEL come on if you get the race "cat" with the headers and not if you just get the headers? if the 2 sensors go on the header before the cat why does it matter if i take the cat off? im confused :?

 

^^^tis a good question. does the flex pipe have any cat properties? :?

 

No, I got my setup used so I don't have any gaskets. I've been told that you don't need to replace your exhaust manifold gasket unless it's damaged though, it's made of metal.

So what gaskets do I need? Anyone?

 

the second o2 sensor is there to check the emissions in the tail pipe so the computer can vary spark and fuel to keep it all clean. With the "race cat" that sensor is going to everything WAY out of spec and think the worst is happened when it can't adjust the engine back to normal... so it has a fit and throws a CEL at you to let you know it thinks there is something wrong.
