Hi. What exhaust system did you put the X-pipe on? Borla "S" ? If yes did it get louder? did it get rid of the drone? What did it change? I have the Borla "S" and its just way to droney and LOUD. Hard to talk on the phone in the car etc. I was going to switch to the Corsa but do love the sound of the Borla just wish it was about 30 % quiter.
