Got a y pipe from a guy on here, and went to get it put on.... guy didn't want to do it because there was no O2 bung on the new one. Is this normal? Should I have him put a bung in? tried to search but didn't really find what I was looking for. Thanks in advance.
 
Sounds like you got an OBD-I pipe with no secondary O2. You can just put a bung in, or get a newer y-pipe. Or get MIL eliminators.

he told me not having the rear 02 would screw up the computer, and it would mess up the amount of fuel sent to the engine. Is this true. I would just get the miliminator otherwise, but don't want it running like dump.

That is incorrect.

The secondary O2's only monitor the precat performance. You can use MIL Eliminators on them.
 
95's do have a spot for a bung, just is filled with a super bolt like thing....at least that is how mine is.
 
my 98.5 have O2 (two on the pre-cats and one on the y-pipe) i bought a msds used without bung so right now my y-pipe O2 is unplug until i found a solution, car seem to run normal but im waiting to put a MIL on it cause now i have a CEL
