Well after thinking about it for a while, I'm thinking that my straight pipe is not benefiting from the lack of a cat and it's making the car run rich. Other possibility is that it's fine this way and BOTH of the manifold o2 sensors are burned out, which makes no sense. So I'm putting a highflow cat back on with no muffler, so basically a straight pipe with a cat so we'll see how it goes. Any ideas?

Forgot to add, error codes are:
System too rich, bank 1
System too rich, bank 2
Cataytic inefficiency (duh)
fan switch caused a code too, oh well
Needing help with diagnosing the problem.C.
