Question for those who like Flowmasters...

I just put on a set of Dynomax ultra flows and I'm not happy with the sound. They are loud just don't like the tone. My brother has the original 40s on his mild 340 duster and it sounds good. However, I am trying to decide on either the Super 44s or the original 40 series mufflers for my 416 stroker....also running TTI step headers and 2.5" all the way back with an X pipe if that matters. I have not heard the Super 44s in person though...does anyone run them and how do they sound?
