My understanding is Ford went to a 1.5 inch connection for the exhaust coming out of each bank. The Y pipe gets rid of this restriction and gives better mpg.
Do the 2000's have this restriction? My understanding is Ford did this to eliminate exhaust flutter.
The other question is what oil? I see they recommend 5w-20. This seems very light for towing.
