Nismo exhaust install possibly went wrong. Fitment issues from NismotoBase?

So I bought a low mile used Nismo exhaust from a forum member on here and nothing seems to be modified from factory. Awesome exhaust for the money IMOP. Seems to wake the car up a little. Or it could just be wishful thinking. So I paid a local shop around Columbus to swap my stock exhaust for the Nismo one that I purchased.

Everything seemed great until after a week or so, then I started to notice that one of the sides of the exhaust seems to stick out a 1/2 inch more then the other side of the exhaust. After I had the exhaust installed, one of the shop managers said everything mounted up perfect except one side, but it shouldn't effect anything.

I took a few pictures but is this normal for the factory Nismo exhaust to not perfectly fit on the base model cars? I didn't read anything about the Nismo exhaust tips extending more then one another.

Maybe I'm making to big of a deal out of things but I would like the exhaust to fit as close to factory as possible and it's starting to bug the **** out of me. I did notice (pictures below) on the driver side exhaust section, one of the exhaust peg bracket is just hanging not connected to anything. What do you think?
