finally doing headers, questions, HELP.
finally doing headers, questions, HELP. so my setup will be...coated pacesetter lts, magnaflow catback, pacesetter y pipe, stage 8 locking header bolts, havent decided on gaskets yet but what else do i need? what about 02 extensions? im 99% sure i need these, and i need 1 or 2? also what length? i know these are noob questions but dont have time to go look and figure it out myself because i would like to get stuff ordered ASAP.
Yes, you do need o2 extensions. You will need two, but I have heard of some people getting away with 1.... But Id get the two just to be safe (its what I do). Not sure on the length, but they dont need to be killer long.
Order yourself some Felpro gaskets or Stock replacements, they work great.
EDIT : Good choice on the stage 8 locking bolts too, you wont regret it.

nvm the kit comes with 02 extensions. do you know a site i could order oem gaskets? i didnt really have luck finding any online and dont feel like putting up with bullshit from a dealership.
I just used the bolts that came with the headers. After I retorqued them two different times within 100mi, they have not came loosein 2500mi. Also pretty sure you need two o2 extensions.

Hey, I think you are going to need 2 extension's no matter if you are obd1 or obd2. A good way to check is to pop the hood and see if you have one on both banks. Obd2 cars have 4 o2 sensors total and are going to have dual cat's w/ an o2 sensor behind each cat. obd1 is just going to have have 2 o2 sensors and 1 cat, w/ nothing after the cat.
I spliced the o2 wires with i believe it was 18 guage? automotive wire to make them longer......very cheap and works the same just gotta tape it with automotive/high temp ductape and make sure its water tight and you're good to go. just my .02 if you need extensions..
Yeah, even if you have one cat you still have 2 O2 sensors. One in each manifold no matter what.
In OBDI cars there is 2, just two pre-cat O2 sensors to tell the PCM how the engine is running, and what changes are needed if any to the A/F ratio.
In OBDII cars there is 4, 2 pre-cat and 2 post-cat (the 2 pre-cat O2s actually take readings on the A/F and tell the engine how to run like stated before, the post-cat O2s only check to see if the cat is working).

If you want to confirm what connector you have (I forgot what years have what) you can just look under the car and see what it looks like (flat, or 4 pin square)...
I am almost positive yours is also a 4 pin though, just not 100% (real damn tired too).
