My guess is no , you don't get better fuel economy . The faster the exhaust is let out the faster the fuel is let in , you'll get worse fuel mileage with dual exhaust . That's just my theory . I would hope the factory spends millions on fine tuning our vehicles , thus the factory set up is the only way to go . I don't know any of this for a fact , but its my guess .
