Exhaust Manifold Torque
Cobalt Extruded Honed Manifold 19131972 Description
This Extruded Honed Exhaust Manifold flows 30cfm more than the stock manifold. You can expect about a 4hp and 6ft/lbs of torque from it. There is a definite performance gain from it and it shows in the upper rpm range and in the 'seat' dyno. You'll also notice a different sound from the exhaust
