Not sure if it helps but I just switched out my std back boxes for Quiksilver straight through back boxes and that resulted in a decent noise improvement sounds deeper and more like a V8 should, but it osby no means “loud” so I would say the rest of the standard system is doing a good job of keeping the noise levels down so putting the standard central box will definitely subdue it....
