Hey guys, I did some research and couldn't find my answer. I have to weld two bung holes onto my aftermarket header for my two Oxygen senors. My questions are:

1. For my Primary O2 sensor, Can I weld it anywhere on my header before my Secondary O2?

2. For my Secondary O2, I'm thinking about having a bung hole welded to the mid-pipe so hopefully my secondary O2 CEL will turn off?

The shop will be welding the holes onto my header. Thank you guys for your time. Any tips or answers will help.

Thanks again

Uh no. The second O2 is supposed to go after the cat. So I'm guessing you got rid of yours?

Yeah i did. We dont have to run at cat do we?

What do you think the second O2 sensor is looking for? You will still throw a CEL if you continue with your plan.

I could try that. Ive seen people try the cat delete test pipe.

I was wondering the Catalytics that dont have O2 holes. Shops can weld bung holes in them and theyll be okay?

Test pipes come with O2 bungs. Some with 2.
