you do know the cat's are in different places on tbi and turbo cars, on my 94, tbi the cat is in the downpipe and on my 89 turbo the cat is further back kinda under the center console area. I assume when you say turbo exhaust you mean one off of a turbo shadow. but from which cat are you going back from???
