cut out the resonators, that will increase volume by 20%. U can have someone fab up a custom mandrel bent exhaust too. Or get the Megan catback.

Most setups ive heard give or take sound about the same Dinan, Gintani,Megan, straight piped....not including the Akra setup cuz that has an X pipe which changes the tone and reduces fludder.
