Default 99 TA Question - 02 sensors

How many 02 sensors are there on an 99 TA? Theres one for sale here and the check engine light is on. Guys telling me it's just because there and aftermarket exhaust on. Doesnt give me a warm fuzzy feeling parting with cash with a dummy light on. Otherwise it ran well.

Aftermarket exhaust shouldn't cause it...check for no cats....

If I recall they have two near the cats.
