CAT question

[Redmachine]

this is a question for my N/T brethren.... on your aftermarket cat did you get it with or without the o2 bung? I see it is after the cat on stock exhaust but would it be better to get the cat with o2 equipment? Sorry if it has been brought up before but I get tired of reading 80 pages with the words cat and bung

their is no o2 sensor bung on my car. only sensors for o2 i have are before and after the cat, but not directly on it.

Thank you for your reply. I know about the one on the exhuast manifold and the one about six inches behind the cat i was just wondering if the aftermarket cat could use that second o2 sensor or should I just keep it after the cat

keep it after
