Just will say (again) that every person I've known with J-pipes wished they had done 4-into-4's. Issues with welds breaking, pipes sagging/not staying in alignment, etc. They were more common in the past where cars were more donor builds. But now 4-into-4's are far more common. For several reasons. An open top car with side pipes is going to be a loud environment no matter what you do. Maybe need to come to terms with that. Not saying cats are a bad idea. But might not make the difference you think. Another thing to put on your list of considerations. If you go EFI, which many are doing now even with SBF's, you will need O2 sensors on your headers. 4-into-4's with collectors solves that perfectly.

BTW, all you guys that are happy with your J-pipe setups, don't flame me. Just reporting what I've seen and heard.
