It took 90 min. To install , well made. Driving I could tell of increase of power and I like the sound when I step on it . I am very pleased , well worth it.

Of coarse you won't notice any HP gain. You will notice much improved throttle response and paired with an exhaust this thing really wakes the car up. My GS350 F sport now sounds like it should without the crappy sound generator.
