Default Flat or square O2 extensions?

Simple question. Any takers?

It's a 94 BTW, so I only need fronts, but do I need one or two extensions seeing as how 94's only had 1 cat?

I could, but if it falls apart down the road I'd just be kicking myself for doing something half assed when I could have gotten it all done the right way the first time. And it'll look better this way, like factory, kind of.

You could, but some people argue that crimp connectors affect the resistance values of the wiring.

The cheap *** wiring kit that came with my pacesetters was all the persuasion I needed to get extensions as well.

You don't ever want to alter the wires attached to the O2s. They are an important part of how the O2s work by drawing in reference air between the wire and insulation. They also use stainless steel wire. If you want to do your own extending, do it on the car's harness side. Extensions keep you from hacking up the car's harness (always a good thing).

You really only need one, on the passenger side. You need the flat one. I got a new one for sale.

Yeah you only need a few inches on the pass. side. Depending on your setup, driver side should fit fine (mine fit but was a bit tight so I made my own extensions. Like 8" on one side and 10" on the other side, way too long but it works.. one of these days I'm going to re-do them for a perfect fit)

I ordered 2 24 inch extensions the other night. If I end up not needing one I'll just put it in the sale section.

It's just easier to ask people who know from experience than get it on jack stands and get coated in oil.

I didn't know if I would need one or two, so I played it safe. It's just wiring.
