Definitely don't waste your money on a good rear o2 sensor. Since you are going to have a bung for the o2 sensor after the Cat. Sometimes they can be very difficult to get out, and you might break it. Just put whatever you want back there in terms of cheap o2 sensors lol.

Definitely stick with the AC Delco for the rear exhaust manifold though.

 

"Since you are going to have a bung for the o2 sensor after the Cat. Sometimes they can be very difficult to get out, and you might break it."

I'm not exactly sure what this means. Doesn't my new zzp downpipe come with a new bung?

 

Yes, and you are going to try to remove your OLD o2 sensor from your stock downpipe to put into the ZZP Downpipe.

You MIGHT break the o2 sensor taking it out.

So keep in mind you will need something for that hole. Be it a really cheap o2 sensor, or an o2 sensor faker, etc.

Or your stock one might pop right out no problem, lol.

 

Oh ok I see Thanks dude

 

I got fortunate with my DP swap. I got the old one out, hit the O2 with some PBBlaser and with the O2 sensor socket, it spun right off. But Chibi is right, if it does not come out cleanly, the O2 that goes into the DP, just get a cheap one that fits.

 

Will do!

Hey.. so how long does it usually take "Will" overkill to respond to an email? Does it take a couple weeks to ship also? I ordered it last friday and haven't had a response from him yet. But my credit card has already been charged..

 

Will does these as a side job and he lives in Canada.

I would try another email or two. Could take a little while honestly to even get to you. Canada Post has been really crappy lately.
