Your manifold accumulates engine gases from all four cylinders, but when your header is cracked, you're not getting a balanced exhaust pulse. This causes lazy accelerations, especially uphill, but Nova exhaust headers from AutoZone let your engine breathe freely. Lowering your output gas pressure lets you fully utilize all that wasted torque, and drivers who upgrade feel a considerable difference in the way their cars respond.
