My logic for getting a catless AA x-pipe and not just hacking them off, was to ensure I could put the car back to stock 100% IF I ever sold it....but that's not happening any time soon
I saw a rewelded OEM xpipe that was re-welded with good precision, I doubt the dealer would even know. If itis just the primary cats that are cut and it was a good clean cut you could return it to stock and get away with it.
