It replaces the OEM system from after the primary cat to the OEM suitcase muffler. Adds an X pipe to the system as well as eliminates the flattened portion of OEM exhaust pipe under the rear axle.
From what others have said it creates a deep exhaust note. I don't think it'll give much of anything in the way of power.
Borla 60606. I'm going to use a decibel/wavelength meter and do a before and after to see how much it changes the note.
