Default Help me pick a Muffler/Resonator for FI

I know this is a topic with a lot of opinions but I need some help finding a muffler/resonator for my 408 s475 setup. Im running 3" exhaust with a ( I am ashamed to say) Flomaster muffler and it sounds like small kittens getting slaughtered! Im looking for something that flows great and has a good deep sound to it. Any ideas?

Dynomax ultraflow oval. Straight through, quiet, and sound good.

I run a magnaflow with a cutout so when the cutouts open there is no exhaust but and open downpipe. If the cutout is closed it goint through the stock magnaflow catback and it still puts down 600 plus rwhp on only 10 lbs boost stock CI!!!

I really like the open DP idea but I forgot to mention that it is a DD and the wife would want to take her new Corolla S everywhere I see a lot of people using the Dynomax bullets but i just cant find any sound vids. I thought with as much piping as i have it wouldnt sound like a Sprint Cup car but i was wrong. Has anyone tried glasspacks? Thanks for the input guys, anymore suggestions?

When i added the dynomax bullets, it did cut down a little bit on the noise/drone.... but not much.....
