This is the Gruppe M Version 3 exhaust... The sound from the interior at around 1:15 is pretty badass... I like it because its different from most NSX's with boomy aftermarket exhausts like the Taitec and Comptech.

This second video is with straight pipes I believe which explains why its so unbelievably loud. The pitch is good, but the sound doesn't rev as high as I'd like it to.

This is some unknown exhaust from a JDM NSX. Nevermind the spouts of fire, the sound at 0:14 is x 29384

The first one sounds great inside the car. From outside it sounds like a fart bucket.
