I have had it about 3 months and the muffler is rattling when it's cold. This isn't a big deal (for now) since when the exhaust warms up the rattle goes away. I have also replaced the stock cat with a high flow one from solo-performance which has caused some drone around 2700 rpm which wasn't there with the stock converter. Other than that the system sounds great and the gains in performance were noticeable especially when paired with a high flow cat.
