Default Pacesetter Header Questions

Ok here is the deal.

I bought my 95 ta from california, it only has one cat converter. I just received my pacesetter headers with air and egr hook ups. I Will be converting to 2 cat converters. I am having a muffler shop make me my own catted y pipe with cats i provide.

My car should only have 2 o2's right? Are these on the headers themselves or the stock y pipe?

If they are on the stock y pipe, then i will need the muffler shop to weld me some 02 sensor bungs, on the new y pipe and then order WHAT O2 extensions?

Here is a list of extensions....

125-109009 Oxygen Sensor Extension, 42" Square 4-Pin (Rear Sensor on 1995-1997 dual cat LT1 F-body, Front & Rear on 1998-2002 LS1 F-Body) $25.00 Buy Wish

Alright i finally found out what i need to do, since i have the 95 lt1 obd1, the car wont read anything after the cats, so all i have to do is get the o2 extension flat pin 24"

(part number - 125-109011 at thunder racing)

You have the correct extensions. I am not clear on your other question. If you received your headers, you should see that the O2 bungs are in the collectors of the headers already.

where do you live. if you dont have local emissions inspections you could run no cats and then cap the air and egr off and take the air pump off and free up some weight

12" flat 4 wire extension for driver's side and either the 12" or 24" flat 4 wire extension for the passenger side. 24" extension on the driver's side will leave you with a lot of extra wire to secure and you don't need that.

Just to be sure before im about to put the order in this is what i need right? One for the passenger side and one for the driver side? This is the only flat pin i found so could i just get 2 of these and use em both for each side?

Where are you looking? I already showed the Summit part # for the 12" extension is CEI-109010. Go to their page and search on the part #. It's $21.95

12" Extension
