i just got a Y8 header for my Y7...

two things... the O2 sensor is way down the header unlike my Y7... can i just extend this with a regular wire?? and what do i do about the O2 sensor after the cat? can i just hook both wires to the first O2 sensor? what would happen if i didnt hook the second O2 sensor to anything?

any answers would be appreciated... i wanna throw this thing on tomorow and i'd like to drive it lol

i dont see why you couldn't extend the wires

u have the same car as me lol

anyway... what about the second sensor???

y8 has a separate catalytic converter, and i believe that is what the second sensor is for... the y7 (if im not mistaken) has the catalytic converter built on to the exhaust manifold

yes yes... no one answers my questions

the Y8 has thecat under the car... my problem is that the pre cat 02 sensor has a place to go (on the Y8 header) but theres no O2 bung on my hiflo cat for an O2 sensor... im wondering what the second one does and if i can drive the car with out it...

yes you can drive without it but no it wont pass smog.... IMO get a header made for your car

in canada he'd still pass as long as the cat was in the system somewhere

i dont have smog... i live in Northern ontario...

so this means i dont need the after cat sensor?? very nice... i will get it installed later but as long as it will run fine and strong without it in, im glad...

thanks
