Jekyll & Hyde exhaust after repair suddenly quieter

Moin, I have a strange problem. I have a Forty Eight with Jekyll & Hyde auspuff (with original HD curvature). I have had in combination with a Thunderbike air filter and 8ballcustoms mapping to start a really core sound. After a workshop visit at Harley due to defective injection nozzles HD has played the original mapping on it and just changed the injection nozzles. All so far so good. The mapping of 8ball was played on it again however klin gt the machine is different now. Still loud but not so kernely anymore. I listened to and compare tens of videos I had from my machine on the phone, also with Harley I was and also they heard that the exhaust now sounds different. How can that be? What could the problem be? Is it possible that the crackers were open before and now too and that sounds different for that? I’m very grateful for tips… I can’t explain it. ps. the flaps in the outp uff I’ve already checked they’re both open, that’s not why it’s
