Hello Guys, I have a 2014 C63 with the performance package plus. Its already 4000KM. Sometime i notice when i push the throttle down on neutral or park, the car does not sound as loud as sometimes. sometimes i would hear the end of the roar which sounds like an explosive roar, and sometimes sounds loud but not as loud. I also noticed when the car has less then a quarter tank of petrol it sounds much quiter and then as soon as i fill it up, it becomes loud as before. weird huh ? any suggestions or thoughts

Thanks.

like burping a baby you gotta learn to burb the c63..don't just WOT it in N or Park, slap the gas pedal so it quickly jumps upto 3-5k and it'll scream..play with it a bit, or if you want get upto like 2-3km an hour and put it into N and WOT it, it'll goto 7k
