Just curious, but why go 3" for the increase in power if you are not going to go headers and custom tune? To me that seems the only reason why I would go 3".... Otherwise you're not getting the full potential from it. I would think going 2.5" true dual would be a little cheaper and be what you're looking for. But, what do I know? Haha, im not the smartest guy on here. Someone will know better prob
