Quite a few people have now moved from quasi-duals to true duals, but I still haven't heard anyone say "it made my car feel so much faster!" or "I ran my car at the track and lost 2/10's" or "I dynoed at 180-something horsepower." So whats up? Does the Duratec really benefit from true-duals versus a quality quasi-dual exhaust ala Borla/Bassani/Brullen?
