i recently got my jet-hot long tube headers and my next move is to order my o2 extensions my only question is which ones would fit my 96 t/a flat or squared? i have a feeling the square ones would since my friends 94 has flat since his car is an OBD1 im sure my OBD 2 would need the opposite anyway if some one can help please let me know.thanx

The easiest way to find out is to look under the hood. They're eay to see on the passenger side, at least on a Camaro.
