y pipe

[mef18352]

I saw on ebay that some one was selling an offroad y pipe from the sho shop it eliminated the cats. I would like to build my own but my question is what do you do with the O2 sensors?

The pipe has bungs for the O2 sensors. At least it should, I have that pipe on my car and they are there. The pipe works quite well, but it makes the car sound raspy.

Thank you for the input I couldn't see them in th e pic that was shown. Wouldn't two O2 sensors without the cat in between be redundant though? or does it just use two?

Our car uses 2 but 1 on each bank before the cats. So it makes no difference if the cats are there or not.

True dat...

Thank I was not aware that it only had them before the cats, I just put true dual exhaust on my dodge 1500 and that has it before and after and I figured the sho was gonna be the same since it listed two sensors

O2 sensors AFTER the cats are for ODBII vehicles. 96 and newer, basically.
