Whats up guys. Finally got my headers installed and bolted in. Just have a question about the o2 sensors. So i pulled out the 4 sensors, 2 from the headers 2 out of the cats. I am not going to be running cats for awhile and i was wondering if it will run fine with just the two o2 sensors that bolt in to the headers? or do i need those other 2?

 

define "awhile"

 

i assume this is obd2, correct?

 

lol im debating whether or not to even put them back in. and yes its obd2

 

Tune em out

 

^ what he said but check ur emissions laws first

 

ok thanks for the info. and 94transam i live in cali so everything about my exhaust is illegal lol

 

Wait, you have a 94? Is that a typo?

 

wtf??

 

the ones in front of the cats with the flat connectors are needed. the ones behind the cats with the square connectors arent needed and can be tuned out. the ones with the square connectors are used to monitor the cats performance so if your gonna be running cats you can leave em in.
