As with any exhaust video, a parked revving car doesn’t the way it does under load. You can hear the general characteristics though which are rumbly on idle, silent through 2500rpm, then a nice exotic wail 2500-3500rpm. I absolutely love this setup because at any cruising speed its in the silent sub 2500 zone and sounds stock, but as you push it you get a nice little scream before each upshift. No drone whatsoever.
Also, it’s much quieter in person, especially at idle. You have to stick your ear directly up to the tips to hear the burble when its parked. I am coming from a vq35 powered car and I think the j32 sounds much much better. A lot more exotic and less vacuum cleaner drone through the lower revs.
