Ok guys, i bought two magnapacks (2 1/2", 14") for my diesel but im curious as to how it one will sound on my 06 5.4. Since i have the Magnaflow on there now (its a 18" case) how much of a difference would the Magnapack sound on an otherwise stock system (putting the mangapack in place of the magnaflow that was in place of the stock muffler).

 

I ran true dualed 11"s on my old 2004, sounded real nice and was barely loud inside. I think that is why I changed them out, got tired of the quiet inside .
