What would flow better true dual or a bigger single pipe that split to dual? Also if anyone knows if you have to have special headers or exhaust if you get a supercharger. I'm not getting one anytime soon but I don't want to have to go back and spend more money if I decide to get it.
its all about exhaust velocity. an inproperly setup true dual system could be less efficient than a single pipe exhaust system and vise versa. pipe size diameter, number of bends, and exhaust components all play a factor in a good exhaust system.
