Short bullet mufflers???
if your tryin just to decrease the rasp, then this is what will work:

it decreases cabin drone and also delivers more torque.
it will also decrease your rasp you currently have.

As for those header inserts, im not too keen on them, but i might be willing to try it. Have you used these personally or are you just speculating based on the manufacturer's claims?
You won't get a muffler with a 3" diamter as you'll need it to have a 3" core aswell so 4" would be the smallest, but a short muffler with only 1/2" of packing will not help reduce rasp as there would be nothing to it. It would however affect the exhaust pressure wave. So this again brings it round to getting high flow cats, check out Random Technology's 7000 Series Metal Matrix ones 3" inlet/outlet 4" diameter.
