shouldn't be much more raspier (if any at all) if you stay with OEM cats.
as for sound, i think it mainly depends on pipe diameter and muffler restriction. since you're staying with the oem muffler, this leaves pipe diameter.
increasing pipe diameter will probably deepen the tone (due to slower exhaust velocity?).
