Hello everyone. I'm removing the cat and am going to put a new mid pipe in.
My question is, do I still need the downstream oxygen sensor?
A guys has an off road H for sale, but it has an upstream and a downstream O2 port. Can I just block off the downstream
If the mid pipe has the bungs for the upstream and downstream O2 sensors then it is for a 94 and up car. If it is for a 94/95 then it will physically fit in a Fox car so just plug the rear bungs. I am not guaranteeing that you will not have to make some adjustments but it should bolt up.
Sounds like it's for a 94+ car if it has downstream bungs (Unless they were added). You really want to make sure what it's for because 96+ pipes won't work
