HELICAL VALVES Fabspeed chose to use Helical Valves on Fabspeed 991 GT3 / GT3 RS track exhaust systems for their unprecedented quality - which have been proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, and many more. Helical valves are an integral part of Fabspeed Side Muffler Bypass pipes, opening and closing with precision to control the 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 Fabspeed Long Tube Competition Headers - allowing them to read all cylinders while maximizing the performance of the collector. This design will replace Fabspeed existing SMBP's allowing you to upgrade to Fabspeed Long Tube Race Header design at any time in the future.
