Those are the ebay special pipes. I had 2 sets of them and they crack in that same spot where yours are welded. They usually bust wide open. I would leave them on since they've been pro welded now lol.
Plus taking them off you would lose like 6hp!!

to jump on the bandwagon, yes, resonated TP's. the rattling sound could be that crack depending on how bad it truly is, sometimes a cracked pipe will rattle under load since those two cracked pieces of metal will contact with each other.

so since 0327 doesn't throw an SES light, the only way to trouble shoot it is to run a diagnostic on the Z? are there any telltale signs I should look further into? also, OP, with the shotty test pipes and the knock sensor issue, have you considered doing any other research on whether the car was abused further before you purchased it?
