I drive it about the same, I've tried to drive less aggressive but still have the same result. I thought it maybe something wrong, but it looks like everyone has the same result. Also, those who drive 330's that rubber tube that used to go into the stock exhaust to control the flap, did you put something up into the tube to stop the airflow? My mechanic put a screw up to seal it. I wonder what that was for.
