Based on YouTube videos, Fast Intentions or Berk sounds like the car was meant to be that sound from the factory. Almost every other exhaust Invidia, AAM, Amuse, Meisterchaft, etc all sound aftermarket and alter the sound completely. HFC seem to be necessary because it's apparently the most restrictive part of the entire exhaust system.
