I wont say whats best or worst rankings, but I know ARH 1 7/8" headers and Magnaflow 16483 (3" system) sounds wicked with no drone at all. I didnt have my exhaust done at adm but I listen to cavermans one time witht Kooks and the same catback and I was hooked. So buy ARH or Kooks, only issue seems to be with kooks is hitting the steering linkage but that is hit or miss.
