If someone is overly concerned about passing and are near limit you should do what I did and go to a custom shop to make some exhaust tips that curve downwards.

This takes away about 4 db of sound which is significant. At Tremblant I got blackflagged (they are at 92db on the track) for passing at 92.4 db and that's why I had them custom made. If your exhaust tips are removable like mine that is. My AA tips are removable and I just slide these other ones in.

Looks awful but gets the job done.
