How do you think, if I remove these tab connections on the pic:

will it decrease the drone I get on load at 2000-3000 rpm? I believe these tabs can transfer the drone to the cabin as I had Berk's HFC before and it didn't make such hollow drone, though it had the same sound level outside (and Berk's weren't connected with these tabs).

in case if it won't help, maybe I need to change my additional Moroso Spiral Flow resonators (installed between ART pipes and Borla) to something more efficient?

and what else can be done to reduce drone inside of the cabin? maybe some exhaust wrap, or sound deadening?
