Sound dampener / baffle for 88db limit at Lime Rock Park

Hi M3post - I am running full Akrapovic Evolution exhaust which in theory maxes out ~93.5db. Lime Rock apparently has a strict 88db limit (I have never been there). Is there a go-to baffle or "Laguna pipe" I can slip onto the Akra Evo? I am not looking to swap back to OEM exhaust simply for this track day...

Do you plan to go regularly to more events in the future with that db limit?
I don't know specifics of Lime Rock for how it works, I assume sound meter in certain area(s) like my local track. If it's for a one off day, I'd be tempted to just lift in that spot. Not ideal, but to fuss around swapping exhausts or fabing some type of Laguna pipe for 1 day seems like a waste, imo.

Fair question. I’d love to go more regularly and the only reason I haven’t yet is because of this noise limit/exhaust. I am debating trying to just lift and see how strict it is during one event, but wanted to see what my other options are for sound muffling.

I believe they check at inspection with a decibel meter so I’d grab a decibel meter and check while someone revs and see if you’re over the limit.
