It's not entirely stock sound, it's the stock sound but implemented into Bartek's special sound system (it's actually a big difference). Also It's very debatable whether it should use the NSX sound or not. Unlike the Infernus, NSX is not a super car. I made this decision as a little easter egg thing.
Infernus based on Honda NSX and other car (not remember which), maybe is one of reasons put nsx sound. Anyway you can add other supercar sound, not nsx.
Almost all cars on server using custom sound, infernus not. Kinda sadly.

It can be called custom, since it was edited to work with our loop based sound system. I see no problem with Huntley and Infernus using SA sound samples. Just compare original Infernus sound with our sound.
