94 t100 airbag sensor light

Since I had new stock exhaust system put at midas, amoung my problems the airbag sensor light staying on all the time. My shop will do a complimentary code tomorrow but I think the remedy will be costly.
They think the problem is in the steering column. Is there something silly to look for that the muffler shop might have done to cause this? I've already replaced an O2 sensor (check engine light) that occured as soon as the truck got arround the block I went back and asked: "Whats going on here?
They allready looked at it and where little help.

They pulled a srs code. Found code 22 stored. Stated normal operation, cleared light and it stayed off. $37.00 ...great
