Question:

How do I know if I need the catalytic converter with o2 port and air tube. One has them, the other does not.

Actually, both MagnaFlow catalytic converter # MF93649 and # MF49690 will look identical. And they do have O2 ports so that will be updated. The difference is the quality of the materials used inside the converters. For OEM grade you would use # MF49690. And for direct fit that is more economical use # MF93649. Both are 49-state legal.
