I noticed your in CA, did you do the AWE exhaust as cat back?

Many people have the AWE touring exhaust. Quiet for normal cruising, no drone on the highway and loud when you're on the gas.

I paid around $2K for my used exhaust but that included a S7 rear valance to convert from a duel outlet to a quad. It looks like the choices for your 2016 A7 is a chrome or black tips.

I'm interested in doing an exhaust upgrade on my 2017 S6. My choices are AWE or Milltek. I do have a question for all of you who have done this mod to an otherwise stock S6:

Other than a much improved exhaust note, what kind of performance gain have you noticed? Is it a truly noticeable increase or just a slight improvement over stock? I realize exhaust alone typically doesn't really add that much of bump but I'm curious to hear the feedback.
