major different FACTORY catbacks from nissan. The 2+2 received an exhaust using a much larger muffler chamber and longer pipes. I have also had a sneaking suspicion that there were different tips on factory mufflers. I guess if there are, it would be due to a change of supplier throughout production. Dont be quick to judge on this one guys. Think of how much stuff changed subtly here and there on these cars. I know I'll be looking more carefully next time i stroll through a parking lot. Parts can and do change without part number changes or revision levels. I've seen people on manufacturing floors change things slightly because they find easier ways. These things slip through the cracks sometimes.
