I'm considering going for a new RS3 once my current S3 PCP deal ends in a few months. I was tempted with the sports exhaust when it was an option for £1k but it is now only available with mag-ride which makes it £1700. I am not interested in mag-ride so is the sports exhaust worth the extra £1700? What difference is there between the standard and sports exhausts? Is the sports one much louder?
