o2 sensor? New exhaust!

[jc Kyle]

Ok,

I'm sure this is a newb/repeated question, but I did a search and didn't find what I was looking for.

Currently in my apartment I have a 3 inch magnaflow catback exhaust (the ad said for a v8, but the people said it'd fit fine if I got a 3inch cat. this seems right, right?)

Anyway, I have the exhaust, 3 inch catco cat, and a 3 inch cutout. All ready to be installed. Now my question is this. What do I do with the line sticking out of the exhaust right after the cat? That is the o2 sensor right? Do i just drill a hole in the exhaust and put it back in there? Do i even have to worry about it? I've heard 02 sims. But what are those, do I need them?

Please tell me, for I want this bad boy in asap!!

thx alot

Not sure about this, but there should be 2 O2 simulators down there, one before the cat and one after. You could get an O2 simulator for after the cat, or you could drill and insert the O2 right after your new cat, try to drill where close to where it was in reference to the stock cat.

would a mechanic shop know what to do with this?

Probably any exhaust shop you take it to
