The reason why it rasp is the midpipes have an h-pipe connection as suppose to a x-pipe union. The Vangaurd has resonators too and it still rasps like the OP stated which is poor design. It sound very deep and throaty for sure, but if you go catless dps, the h-pipe at the midpipes do not cancel out the rasp.
