I was referring to the audible difference but they will also transmit more vibration into the car. Vibration in the car is really only noticeable at idle, more so with the a/c running or if the car is idling rough such as if you have a vacuum leak or something. I had the idle on my car bumped up to 900 rpm to reduce the SC'er rumble at idle well before upgrading the mounts though so I don't really get much vibration at idle but the lower stock idle speed will probably lead to more vibration as indicated by vI6cious.
