i'm considering a dual/dual muffler for my 2000 explorer sport with
4.0 SOHC V6.  i've heard arguments on both sides with no definite
numbers to back up either.  I can't find any good numbers or
testimonials on V6's.  i've heard that flowmasters dont flow as well
as magnaflows, and that the magnaflows offer a little bit of low-end
torque gain (especially on Fords).  anyone with some first-hand
experience have anything to offer?  which one would you recommend for
deepest sound and/or best engine performance?
