I was wondering if i could remove 2 of my 4 cats and pick up a little bit better sound. Would it make it sound like crap? Too loud? Any hp gains. I do know this is not "Spose to be done" but what were to happen if 2 of the 4 fell off one day and i did not know and i put some pipe in the place they were spose to be becuase i did not kno that cats were spose to go there so i just put some normal piping.
