edit: I have been looking on line for parts and a confused. Are there two cats up front on the Gen 2.5 a left and a right?


The CA emissioned ones have precats coming from each exhaust mani, connecting up as a part of the y-pipe.

Assuming you have the pre-cats, another options would be to gut them. There is spacer to move the O2 out from the pipe a little, or you can get an electric thing-a-ma-jig that manipulates the code to the ECU. I think they can be found on 3SI for ~$50 each. Haven't tried either, but plan to if I keep my 95 and rebuild its bottom half.
