Hey guys, I got a quick question! I bought a test pipe for $10 bucks but I just noticed it doesn't have a thing for the 02 senor. But I'm not sure if the test pipe is supposed to have one. So my question is do all Test pipes not have 02 sensor bungs?

 

Just have a shop weld in a o2 bung and your good to go.

 

So test pipes do have 02 sensor bungs on them! Woah how much does that cost?
