With PCA we run 103db days there and my race exhaust, which is nothing special, is apparently teetering on or over the edge of that, so I need to bolt on the elbows at Laguna. It's really simple and effective for what I need. For some reason, even though Thunderhill and
Sonoma Sears Point have a 103db limit all the time, I don't have issues there at all.
Unfortunately, one time I exited the car right after a race and while still helmeted walked past my rear bumper without looking down and put a pretty nasty gash in my shin... words were spoken.
The stock muffler is around 87db so that's my backup on the occasional low-db day with other groups.
