'94 2WD std cab base model
In replacing my cat and exhaust I've found out I need to also replace my header pipe too. There are two listed on the various parts supplier sites and I can't really determine what the difference is (other than a $20 price difference). Anyone know what the diff. is and/or which one I need?
Here's a page with the two options:

Also, my pickup has an O2 sensor before the cat and one after the cat. What does the second O2 sensor do and is it necessary?
