Just as we thought we liked that 580-hp Mcchip RS4 better than the RS6, we stumbled up on this thing and now we are ruined. This is a heavily tricked-out Estoril Blue Audi RS6 Avant packing more than 700 horsepower and boasting a Milltek sport exhaust system that sounds like a machine gun at full chat.

How can you not love this Audi RS6 when it looks that good, goes that fast, and sounds that brilliant?

Now, some people may find that Milltek exhaust system a tad too loud and not in keeping with the discreet looks and feel of the RS6 as a high-performance super touring. But Milltek is kind of a household name, now that Jon Olsson has picked it for his one of a kind Audi RS6. It is really more about the brand name than anything else.
