Anything with cat removal like the hog slayers is going to be loud. Loud is subjective, so it's hard to say what YOU will think. But suffice it to say a lot of people who for example have TORS tried removing the cat and said it's a lot *louder*. Some went back to the cat because it was too loud. Some people have very different ideas of what loud is and i have seen that here forever. So you gotta hear them for yourself. I don't know if the D&D's are sans cat, but if not then the Hog slayers will be considerably louder according to those who've tried it.
