I thought o2 sims were only used on the o2 sensor behind the cat. If that's the case, you wouldn't find them for an obd1 94 camaro. I can't imagine why you'd want to get rid of the o2 sensors on the exhaust manifolds.

i replaced my cat with a straight pipe and lost most of my bottom end,if its not that then what could it be causing my loss?

OBD-I ECU's have no o2 sensors after the cat. they just have them in the manifolds or somewhere before the cat.

I don't know why u wouldve lost ur bottom end if u still have a good muffler... if u have straight pipes, glasspack or anything straight through and the cat was your only producer of backpressure, that could be why u lost bottom end. I think no cat is ok as long as u have the backpressure of a good muffler... anyone can correct me if i'm wrong. :slap:
