Yes it was mounted by the rear o2 sensor. Came with instructions on how to put it on, super easy. Big Daddy's has been around for as long as I can remember and I've heard lots of good things. Some say that the mini cat will eventually get clogged, and at that point I will try to get a free replacement or just buy another one for $49. Either way its better than risking voiding my warranty for a $400 tune that adds hardly any performance. But that's just my personal opinion, each to his own.
