Did any of you guys have sound issues? I was running my RPi x pipe with oem mufflers and I did a 99dp first session 3 laps in then I went and hacked the x pipe at a local muffler shop for 200 bucks. Ran the 2nd session and did a 94db! I couldn't believe it and Dave@Speedventures just told me to short shift going up 5/6 which I did and finally did a 88db. DAMN sound restriction!

Another easy fix for your problems IF your exhausts have tips that can come out like my old Active Autowerke exhaust is to make custom tips at an muffler shop.
I made custom tips that curve and point down to the ground. When I go to track events and they flag me for sound I put on the tips and pass afterwards. They look ugly as ass but can cut up to 5 db's!
