Suggestions Wanted For 408 Stroker Mufflers

You need the right Flowmaster. The Delta Flow 40 series is the right model. They are not too loud, and the sound is unreal. You don't want the standard 40 Series because they are too loud.
Those are the mufflers I went with. I was able to swap the original ones back for them. 2 1/2” and a straight through design. Thanks!
