A LOT of us run them so yes, we would naturally think the are good to have. Most of us run cast dual exhaust manifolds and not so many have true tubular headers. They both help a lot with the flow of exhaust and the cool factor is nice too, especially when viewed from the rear. Mine sounds very mellow with no ratta tat tat that the old split manifolds had. Sorta miss that. I have a muffler with one in-two out so I get just the right amount of back pressure. Take a look at the link below to view them.
