I'd argue it shouldn't as the external audio sounds nothing like a stock 1995 Dodge Viper's exhaust note. Better to look at this mod like a 3rd party exhaust modification, for the time being.
Perhaps the modder listened to a Viper with modified exhaust.
The Viper RT10 engine has a low end growl which the default sound captures. This mod is much higher in pitch.
Like I said, more like a 3rd party exhaust mod
I'm in the same boat, though my mom's isn't stock by any means any more. That one just sounds tinny at the low end and not right. When wound up it doesn't sound as bad, but the low end is totally missing presence. I thought the modified one that A3DR includes with the car actually captures it better.
For reference, my mom's 94 has the cats removed and the stock mufflers replaced with a pair about a third the size, so yeah...it's loud.
As a side note to this, forgive my ignorance, but are transmission sounds separate from the engine sounds or are they baked in? I was listening to some Vortex V10 clips to see what it sounded like for comparison, but it has so much gear whine from the transmission on interior shots that it's hard to make out just the engine sounds. If I were to buy the Vortex and strip the audio (if that's even possible), can I also remove the whine from the interior engine track?
