Car sound?

Hey, Ive just heard some really sick sound on an Audi, it was kinda like an electric sound but much louder. Dont know if it is because filters, exhaust pipe or something else. Would anyone know where I could find more about that? I cant really tell much more as I cant even find that sound on YT or somewhere, but Id like to find it.

different parts of cars makes sounds like engine, front tires of cars while moving from curve turns when pump while driving.

Hey there,
If you are guessing the exhaust or filters, that means that the sound is coming from the back side of the car. It even could be the chasis in the back side while running when the air passes through the cracks in it makes that sound. Did you hit in a speed breaker? Do check that...
