The boost-dump sound is why most people will be picking this over a K&N or similar filter, so I'll say its definitely a good sound. I was worried about it being too loud and ricey, competing with my Borla Exhaust for attention, but it doesn't. That said, the induction sound is also louder, so if you're not a fan of louder whistling on acceleration, this may not be a good call. That boost-vent though...
