Are you speaking of a stock replacement and location cat? I've read on here that they're made but I don't remember by whom. I do remember that Jegs and/or Summit carried them.

Default Why do you want cats anyway, they will claw your interior.

Do you want hi flow, or are you trying to pass an E-test? I just took mine off and put them in a box. They seem to like it better that way. And now I can get to my fuel filter with ease .

I'd like to have some hi-flow replacements like the random tech or magna-flow brands. I see under my hood it says its a true OBD1 car but i also know some cars or most all of the 95's came with OBD2 stuff. Hope i have a true OBD1 car then cats would be a bit more economical.

I'm gonna try to call Randomtech to see what they can do for me.

95s are OBDI with OBD2 connectors, etc. O2 sensors are before the cats on each side, behind the cats are sensors that are not 'active', nor necessary. Of course if you bypass the cats it will not pass the emissions tailpipe sniffer, nor visual inspections. I understand the 95 cats are actually hi-flo so you won't see any gains from changing or deleting them. Disclaimer--the above info is neither reliable, nor is speaker liable (forgot the actual words, close enough I guess).

If the sticker under the hood indicates OBD I (or at least no specific mention of OBD II compliance) then you definitely have a 95 with OBD I codes but will have the OBD II 16 pin connector under the dash. Like mine.

Good info for me and everyone else wondering guys. I think hi-flow replacement cats aren't necessary yet. I'd rather do headers and or gears first and see a definate improvement.
