How Would This Sound??
2002 F-250 5.4L V-8:
Take off stock muffler and tailpipe and put on Flowmaster 40 Series with a 3" turn down pipe....everything else stock....
Loud? Nice rumble? Aggressive?
Your opinions please....

Been there, done that (with a 40 Series Delta Flow). You'll need 8" of pipe after the muffler (per Flowmaster). Sounded really deep, pretty loud outside... but was unbearable in the cab, really loud inside at highway speeds. It would rev though! If you can live with the noise and some bottom-end loss, go for it.
