It sounds like the manuals will be ok with the axle back, as it is more of a straight through pipe from the cats back. If it is an auto then the catback may be better. I am not exactly sure, as my car has a few extra parts. I am not sure where there is a dyno around here, I think there may be one in Watertown. Where do you live?
