RC:

 

In a tunnel, even a Tesla may sound like that. Smiley

My R8 sounds that way all the time and even at slow speeds. Smiley The 911 Turbo S exhaust is not quiet at higher rev figures but it just sounds crappy, like a vacuum cleaner. Also, it isn't only about loudness, it is about sound and not every sound sounds good.

exactly. it is the quality of the sound, not the decibel (only). the deep mechanical grumbling noise .....
