JC. Your losing alot of torque on the bottom because youve eliminated backpressure in the pipes. You can go big on the diesels because they pump alot of air in and out. gas motors need back pressure for takeoff power. Go to a single 3" or a dual 2 1/2 and you see big difference in bottom and mid torque.
