That would be the 1M's (N54T) factory mid pipes. They also have the secondary cats but the resonator is a fake. A friend of mine with a 1M found this out when he and a friend cut it apart! This is also why 1M guys experience drone and why when they install a N55 mid pipe the drone goes away!
1M mid pipe resonator cut apart...
