Which is gonna give me more of a rumble with true duals. I want to wake the neighbors in the morning when going to work on a 4.6L

 

Wow, didn't think people cross shop those two. If all you care about is waking the neighbors, then skip the muffler completely. Don't bother spending the bucks on Bassani unless you care about how it sounds or how it performs. Bassani >> Flowmaster in terms of quality and performance. Sound note/tone is preference, but I dislike Flowmaster.
