Exhaust/muffler
I have a 5.4 F-250 with single in and out 40 series flowmaster. But Iv'e noticed on my brothers 4.6 F150 same muffler his is alot louder then mine his is ran the same as mine. Also my neighbors 5.4 F150 is louder then mine and he had dual 40 series installed. I understand that the duals would be louder but is the big difference between the 4.6 and the 5.4 setup the catalytic? And would buying the Y pipe off of ebay for the 5.4 make a difference in sound? and loudness?
Any thoughts or comments would be appreciated.

I recommend getting a Stans or Ebay y-pipe and have it installed on your SD. The Y-pipe not only increases low end power considerably under 3k rpm it also makes the exhaust much louder as well. After changing the Y-pipe I would not be surprised if its a little too loud for you. I was very surprised about how much the exhaust note changed after I installed mine.
The F-150s have a different more free flowing y-pipe design from factory which will make them sound louder.
