Secondary Cat Delete X-pipe j pipes no muffler no resonator sounds amazing..
I have the A8 though in the Manual my setup would def have drone at 70+ cruising speeds.. However in the A8 I dont get barely any drone until 2100+ RPM which is 82+ MPH.
High flow cats I am not made aware of any that are purposefully made for our cars however nothing a muffler shop couldnt figure out for you. I can tell you deleting the secondary cats make a huge diff in sound.
