any one like to comment on headers on a 4.6 with dual ex catback?i would like to do it if its worth it.need comments on the subject.

 

Headers and cat back? They're the first mods you should do to any truck. I say go for it. With either mod, you will notice a gain in mostly midrange power. Now this dual exhaust you speak of, are you looking for true duals or just a y-pipe? I'd definitely take the y-pipe over the true duals, since the y-pipe lets you keep your low range power. True duals rob low end torque. Either way, I'd say go for it.
