Here's the car at the moment, next up is extractors and exhaust. From what i've read 2.5" from start to end is the way to go, but which extractors is the way to go?

Also, as per my girlfriends request, she doesn't want it to sound like a drone-mobile. Not knowing much about exhaust, what causes the vk/vl commodore drones? i thought somewhere along the lines off toooo big of exhaust or small start (from exhaust manifold) and then big at the end but i could be way wrong.
