You'll still get that "rattling/rasping" sound with aftermarket exhausts running no cats. Just, not as apparent, and hidden/underneath the bigger/bassier sounds the bigger diameter exhaust pipes produce (think short/thin vs long/thick pipes of a pipe-organ, trumpet/tuba, diff keys of a marimba/xylophone, guitar, piano, etc., etc.).
I think you do not quite differentiate between rattling and rasping. Rasp will always be there. Rattling should NOT be there.

The stock exhaust, without cats, both rasps AND rattles. The rasp cannot be eliminated; the rattling can.

If deep, bassy exhausts are what you consider a proper exhaust, then you've never ventured into high end exhausts. Deep, baritone exhausts are universally quiet at high flow, high RPM. Think about it.
