HQ-8715 - Exhaust Venturis

These units create more torque and sometimes horsepower by improving exhaust flow and combatting exhaust reversion. By acting as a continuation of the exhaust port, they can also help realign exhaust pipes.By installing the venturis in the port first, then adding the exhaust gasket before the pipes, they stop the mesh gasket from crushing into the port.

Each set comes complete with James exhaust gaskets # 65324-83
