So I finally got my car up on a lift since I purchased it. A little disappointed. The undercarriage bolts are all badly corroded and some are even broken off so that's going to be fun to get them out.

Anyway the other thing I noticed is there was only 1 bolt from each downpipe to the midpipe. The inner connections were just empty holes. Is there any chance it came from the factory like this? I had it at the GTR dealership for all the 3 year services and the tech didn't say anything? Can it stay like this or do I need to get the right bolts? Pardon my noobness but I've done almost no work on cars myself so this is all new to me.

I'm wondering if the car maybe had a midpipe and then the previous owner put it back to stock. But strange they left the intakes on the car.

If you haven't already, I would also suggest inspecting the nuts behind the flanges on the downpipe side to ensure they're not corroded to the point where a bolt will keep getting stripped, necessitating running a tap through the female side. It just seems strange that the pair were left in that state. It was either a rush job or maybe the previous owner had issues getting bolts in there due to the corrosion.
I have the new gaskets, studs and nuts on order at my local Nissan dealership. Any idea what the thread of those studs are so I can make sure I have the right tap if necessary.

As I'm starting to repair this situation that the previous owner left me with I'm starting to believe that the previous owner had a full cat back on the car and then put it back before trading it in to the dealer. There was also an accessport mount in the car which leads me to believe it was tuned. If they left it tuned for the exhaust but put the factory exhaust back on is there any harm? There is a large amount of carbon that gets deposited on the exhaust tips each time I drive.
