I can speak for the 4" Magnaflow turbo-back - it is really quiet, ....you don't hear it over the engine. I don't think it's any louder than stock. Wish I would have went with MBRP or Silverline. I was replacing a 5" system that was too loud for me personally - lots of resonance. Unfortunately I went too far the other direction! Good luck......
