I'm doing my first HPDE at Sonoma in November and there's a 103db sound limit. With Z1 headers, Berk HFC's, and an Invidia cat-back what are the chances I'll get flagged for being too loud? I have the headers sitting in a box in my trunk and I'm considering adding them after the track day, just to be safe. I figured I'd ask the more experienced among us before deciding.
