Not at all. I have the15 RT A8 and with the Super Track Pack, the car came alive after the exhaust. It sounds like a sports car and very responsive especially when I engage the SPORT function, basically suspending the MDS. I would encourage anyone to get it unless you want really loud. I did let you know that autoanything has an additional 15% off for the next 2 days. They also have some Magnaflow cat backs but I've always had FMs on my vehicles.
