Not sure on that one, my Mustang runs fine with the o2's hooked right to the harness but the o2's were before the cats so it didn't change anything when I removed them. Sounds like Jeff's post would be the way to go for yours. I think the readings would be different without the cats on yours and that might freak out the computer. But you are supposed to reset the computer when you change exhaust setups anyway so you might try it and see what it does before you spend the cash.
