What's up peoples?

I'm looking into buying a test pipe, I have a 94 LS that has 2 02 sensors, but most test pipes that I've found only have a fitting for 1 sensor... what do I do?

Thanks

 

buy an O2 bung, drill a hole and weld it on, or if you dont have the tools to do that, bring it to a muffler shop and pay them to do it.

As far as i knew 94 ls only have one O2 sensor. OBD2 harnesses have 2 O2 sensors. one on the header and one for the catalytic converter. you said its a 94 LS so if you have 2 O2 sensors connections my guess is you have an OBD2 harness. if thats the case you only need to run the one O2 sensor and you can just let the other stay unplugged

 

You only have one O2 sensor. 96 and have 2.

 

He could have a car with California emissions, which had 2 O2 sensors earlier than 1996 model years. I'm not sure what year they started with that, though.

 

Well, here's to answer the question.

You only need one 02sensor in the test pipe. (if you want)
Unless you also want to wire up another wideband 02.

The other 02 goes in your header. (not your cat, test pipe, etc)

 

Just to be safe. Bring it to a Muffler shop, they will weld an o2 sensor bung on your car for like $30-$40.
