From the outside of the car, the Gamma sounds quieter but it has a little more propensity to drone.

From the inside of the car, the V2 is quieter and doesn't drone. But from the outside of the car, the V2 sounds louder.

I hope this is a clear description.

 

so the V2 is both quieter on the inside, AND louder on the outside?

seems like the best of both worlds haha

damn now ill need to look into getting the V2

 

Yes, that's it.
