I had the maddad whisper on my 08 hatch and then on my 12. Absolutely loved the exhaust no drone what so ever. Quiet when you wanted it to be but really opened up at higher rpm's. unfortunately was in an accident about a month ago and decided to try something different and went with the q300. Huge change I love the way the q300 sounds but the drone is crazy compared to any other exhausts I have heard on the hatch. To be honest still getting used to how it sounds and have had to turn up the radio a bit more than I used to but can still manage to talk to other passengers. If I had my choice I would go with the whisper or the street series again but kinda been addicted to the rumble the q300 makes.
