i tried the Dynomax VT muffler on the Nova,with 3" and an X pipe i always liked the sound of the dynomax on the 5.0L Mustangs, these have the flapper in them supposed to be quieter at idle and cruise and then open up at WOT but i find them a little too loud at cruise, they have a really good sound to them not a raspy as a Flowmaster and a bit deeper than a magnaflow. i have always liked magnaflow in the past, but i think i am going to change these ones out for a old school Dymomax
