Actually, I wasn't planning on changing Super 9 packing anytime soon, was talking about when I changed packing on kart engine.
I bet fresh packing really helps with the sound. My Super 9 is 2003 with approx 4900 kilometers on it now, so over 10 years old, probably needs new packing. I will do a comparison when I install the new Tecnigas Next R on my People 50. It's almost the same pipe as on the Super 9 and I believe would fit on the Super 9, or Super 8 50 2T, plus People 50, all basically the same engine.
If and when I change it out, I will try to post pics. Cheers
