i have been looking to upgrade my y pipe which right now is a stock dual cat 96-97. the car had a set of shorty headers and a B&B catback exhaust when i got it and i am thinking of opening up the y pipe. i have to pass emmissions so that is why i cant go with LT headers. basically i have found a few options for the single cat 94-95 y pipe, but not too much for the dual cat and am wondering what would be involved in swapping from the dual cat to single cat y pipe. i know i would have to get a high flow cat but would they bolt up to the exhaust or is there a lot of things that would have to happen for the single cat y pipe to bolt up. any help would really be appreciated. i also want to get the car sounding even meaner than it does, and this should make it a good bit louder i would think right?
