I got this exhaust installed about a month ago and it sounds awesome! I been watching video on YouTube and it's great in person. Isn't obnoxious loud like could wake up the neighbors but it is a deeper and louder volume than stock. And my Infiniti dealership installed it as well but call your dealership because it is OEM part.

My car is an Infiniti Q60 2.0t The exhaust kit sounds great! The sound is deeper and louder than stock. On a cold start, I'd say if the stock exhaust is a 0 and the straight pipes are a 10, this is a 5 or 6. After short time, it reduces to a nice soft burble. Nothing loud or offensive. The car is more responsive. Highly recommend!
