A different back box will release the rumble but if you change the centre section to a straight through pipe, you'll get rid of a cat and a resonator box so it'll make the rumble deeper/bassier

As above;

Changing backbox = Raspy.

Changing midpipe = Bass.

Popular combo seems to be an STI Genome backbox with a straight through middle section.

Depends how loud you want it.
