I have the 3.31 gears. Looked today to make sure lol. I don't get drone at normal driving. Obviously if I put it in 6th gear at 30mph it will drone but who drives like that. There pretty loud when you crack it open. You can talk over them at cruising speeds. I like them I just want something deeper in tone. Planning on either running the bassani or custom making a magnaflow set up using 3" instead.
