Not sure, all it is is the muffler only. Its the round one note the squared looking one like the cat back system (not sure why there are 2 different ones). I originally was going to get the squared one but after they showed me how it sounded and tried the Borla XR1 I liked the S type. From what I've read the XR1 is a lil louder and when I heard it sounded more throaty.That sounds great, I you don't mind me asking, that is the exhaust currently selling for the Sierra correct?
