Anything but a flowmaster? Try an Ikon with the first resonator in place, 2nd resonator delete with an x-pipe in its place.
Maybe try the Euro-Spec muffler with the second res delete? How about a DMS if you want it loud?
Our cars sound awful with straight pipes and a flowmaster is only gunna make it worse.
