Will the 07 4.6 2v sound anything close to a 03 5.4 2valve?

Since i got rid of my 03 i have been missing the nice rumble of an exhaust..

I really liked my exhaust setup on my 03. It was nothing special, a si/do 1 chamber muffler with 3.5 inch stainless tips out the back.

Id like to do the same setup on the new truck, Is there a chance the 07 will be a little louder due to having 2 cats from factory instead of 4 like the 03 had?

What would the difference be in a one chamber knockoff muffler and lets say a magnapack?

 

Much louder with the two cats. A little more aggression than the 5.4L too.
