Phenomenal difference. The videos don't really do the exhaust justice. It's much louder and has a rumble that you can physically feel. Can't comment on the durability of this exhaust, but it sure looks quality. I tried to find a video to justify the purchase but like I said the videos don't justify it. To put on, it's just two books and clips (1 large clip). The big one was the trickiest and I found it easier to remove the nut completely so you can attach the exhaust pipe. The entire assembly was easy and took about 30 minutes with my daughter's "help". Highly recommended. I can't necessarily speak of an increase in performance, but I do feel that it has quicker throttle response. I will give an update 6 months.
