Exhaust rasp? Which new mufflers?
So on my 6.4 I just switched from single 3" areoturbine to having the y-pipe cutout and running duals to a spintech 3000 dual in dual out with tailpipes dumped over the axle. I'm surprised with how much quieter it is and how much rasp I have when getting on it passed half throttle. Any suggestions on what to try? It sounds good under half throttle and is extremely deep.
