What is the difference between YES/NO crossover chamber headers?
Freedom standard true-dual header has an individual header for each cylinder. The front cylinder pushes more than the rear because it gets more air & gas, generating more horsepower. The "Crossover Chamber Header" combines front & rear header cylinders co-mingling, adding heat in the crossover chamber to generate more torque.
Simply put, torque is a way to measure force. Torque is great for short runs. Horsepower, on the other hand, measures the amount of power that is transferred from the engine to the wheels.
