Flowmaster super 44s

Although not apples to apples comparison I had them on my 416, 4-spd Dart. Yes they are prettyloud but just didn't have a nice loud sound in my opinion especially at high RPMs...sounded too raspy. I switched to the original 40 series and they are still loud but a nice loud. If you like the chambered muffler sounds also look at the Dynomax ultra flows. They don't seem to be as loud as FM.
