4 Pipes- Why?

I often wonder what I’m supposed to think when I look at a high-end car like this Cayenne. I guess I’m supposed to be impressed, even envious at the incredible engineering involved, and the wealth/success of a person who can own this. Especially as it isn’t one of the ‘ordinary’ Volkswagen ones, but has the little Porsche badge on the front end, which of course puts the price up by a few thousand.

Unfortunately, my immediate reaction was to wonder why anyone would drive a vehicle that burns so much oil it needs four exhausts to efficiently dispose of the pollution.

A fairly literal case of overkill, there.
