HELICAL VALVES
Fabspeed chose to use Helical Valves on their track exhaust systems for their unprecedented quality, which have been proven by OEM manufacturers like McLaren, Ferrari, Lamborghini, and more.
Helical valves are an integral part of these side muffler bypass pipes, opening and closing with precision to control gas flow and optimizing engine back-pressure for improved performance.
Helical’s extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs, and high-temperature bearings at both ends of the butterfly spindle.
O2 BUNGS
Fabspeed relocated the O2 bungs from the collector of the headers to the side muffler bypass pipes in order to maintain factory-like functionality with their long tube headers. Allowing them to read all cylinders while maximizing the performance of the collector.
This design will replace the existing bypass pipes allowing you to upgrade to a long tube header design at any time in the future.
