3" muffler suggestions

I know this isn't a direct answer to your question. On my Demon I'm running TTIs and will be running 3" with the ultra flows. It has springs moved to frames with mini tub. I plan to have tail pipes made that go over axle to the outside of springs and to run 16" race mufflers in the tail pipes as "resonators". Don't know how loud it'll be but I'm thinking when I get to that point that it should have a nice rumble but not be as raspy.
