  I notice a lot more turbo whistle / woosh from my intake than my exhaust.  You CAN year it through the exhaust, but the bulk of the turbo sound with Jezzie is from under the hood.  Significant difference between the stock airbox and a cone filter.
  

  
  lol, well, with my car, being that the intake enters under the hood, and the exhaust comes out at the firewall..
