Possible Sup-up?

get an aftermarket exhaust like flowmaster or corsa or something like that to make it louder and to go faster chip it, cold air intake, tune it, supercharge or turbo, you can do alot of stuff thats just some ideas

another fast and easy thing you can do is cut out the Catalytic Converter and you can get money for it and then either put a straight pipe or flexi-pipe in it by welding it in there it'll have that lower growl and it will sound fierce

krissy that's all good if you don't need to pass an emissions test . logan you can always add nitrous oxide.
