I am currently running the Bassani FH523SL 4" mufflers on my CVO Ultra. Several years ago when I purchased them they had a nice mellow tone to them, now they are very loud, I pulled the baffles out and rewrapped them expecting to get that nice mellow tone back again, but nope didn't happen, still has that very aggressive loud tone to it. Nor sure what has happened, the baffles still look just as good as new, just very black. Any ideas why these slip ons don:t sound like they use to, I sure miss that low mellow rumble that I use to have. Also I would entertain some new suggestions on some mufflers that has that deep tone to them. I guess I will have to buy some more mufflers, just not sure what to purchase.
Thanks
Jimmy

Have you checked you header bolts? Had this and found my rear header bolts finger tight.

Do you have the Cat in the head pipe?

Have checked header bolts and I have the V&H crossover pipes on it. haven't hanged anything since I put the mufflers on years ago. Mufflers use to have a real deep sound, thought the baffle wrap was bad but it wasn't. So I rewrapped them anyway, There was no difference in sound. Still very loud, doesn't have that low deep sound anymore. I called Bassani and they said I need to give the.baffles a little time to burn in and the insulation will become looser and the deep sound should return. A tight wrap will not produce a deep sound. but you have to wrap it tight to get the baffle back in the caN. I guess I will give it some time and see what happens.

A friend had this issue with his bassani 2/1 and played with different packing before he got it to where he was happy with it.... he did say the more/tighter the packing was the louder it got
