question also here sorry for jumping ur thread but i was going to have my OBX Headers installed today. and the 02 sensor was a screw in and mine are a bolt in. why did lexus do that. the 02 sensor is above the stock cat if i dont add o2 sensors what will be the out come i found 2 on ebay for 30.00 and aliga will hook me up but i really dont see any meaning in adding these headers becides the lil power i will get + my manifold is still leaking. and this will quiet that noise down. but over all i am still working on my 1jz swap should i just have these install for 120.00 or sell them and just keep the leaky exhaust and dump the money in for some 1jz stuff ow ps the car sounds like a truck lmao

 

Spend the money on the 1jz stuff!

 

You need 2 1 wire screw in o2 sensors. Available at any parts store.

But yeah if you are just going to take it out anyway, you might as well not put those on.

 

yo cam how much you want for the header?

gimme a deal on the header and that hood

btw yeah you can just go and buy universal 1-wire o2 sensors at any auto parts store

 

50.00 a pop for 1 i need this header till july

 

The o2 sensor should be ~$28 at autozone.

 

you only *need* 1 o2 sensor. just like I only need one turbo =)

you splice the 1 02 sensor to the 2 stock wires.
