i just bought that plx with the sm arf combo and what im going to do is pull out my o2 sensor and put it in there but you have to put resistors in the line has anyone done this i need help asap

 

Save yourself some grief and go to a muffler shop and have a bung welded in and leave the OE o2 alone.
Make sure the angle of the sensor is pointing downward from 10 to 2 o'clock so condensation moisture will drip off.

 

yup thats what im doing im going to do it tomorrow

 

Do you have a tune?

 

If you have it tuned, just pop out the driver side REAR o2, put it in there, then have the tuner tune out your rear o2's.. Or just go to the damn muffler man..

 

yea its tuned but i still have cats so it wont read right and the back o2s are shut off already im just going to wait im ordering long tubes and y pipe so im just going to do it all at once instead of tuning it 2
