about 02 sensors

I just got some pacesetter longtube headers installed on my 99z.
The auto shop said they didnt need the 02 sensor extensions i bought because they said there wasnt a place for them but the y-pipe. Now my engine light is on.????

What code(s) is it throwing - is it for the rears?

Bring it somewhere, like Auto Zone, and they will read codes for free. 02 extensions are normally for the front - did you delete the cats?

Ok if you bought the pacesetter y then you ditched your cats. You need too pickup some 02 simulators for the rear 2 sensors. The harness its beside the tranny on both side. you will need two of them. As far as the 02 extensions, most people use them on the front sensor bc the wire isnt long enough too reach the harness. Like said above have your codes checked and post for further help.
