Twin cat Exchaust system on an earlier model Does anybody know if the twin cat y-pipe and manifolds from a 97 LT1 would fit on an earlier (93-95) model?
Would the earlier model have the 4 O2 sensors or just the 2 pre cat? and if thats the case would the best solution be to just block the o2 bungs behind the cats?
I'm asking as I no longer own my 97, and have some bits for sale. Someone has asked about my y-pipe and manifolds fitting his earlier single cat model and I would like to help him out if possible.
Thanks

I heard some of the 95s sold in California had dual cats, just like California 95s had the 3.8s in the V6 cars a year before every one else did. It should physically fit, just the rear O2 holes would need to be bolted off like you said, you can buy bolts specific for that purpose.
this is what i was exactly thinking although i dont know what the manifolds on the 93-95s are like i can't see the driver side having that awkward 3 bolt triangle pattern.
