HELICAL VALVES:

Fabspeed chose to use Helical Valves on their 991.2 GT3/RS track exhaust systems for their unprecedented quality.

PORSCHE motorsports AG actually uses HELICAL valves on their GT3 side mufflers and only Fabspeed uses the exact same Helical valve. Same part# same bullet proof quality.

Proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, Pagani, and many more.

Helical valves are an integral part of our 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.

Helical is an aerospace company that also makes exhaust components. Fabspeed Motorsport USA is the USA's exclusive importer/buyer. 

O2 BUNGS:

They relocated the O2 bungs from the collector of the headers to the side muffler bypass pipes in order to maintain factory-like functionality with long tube headers, allowing them to read all cylinders while maximizing the performance of the collector.

This design will replace the existing SMBP's allowing you to upgrade to long tube header design at any time in the future. 

Extra oxygen sensor ports also allow data acquisition at any time. Another added feature only from Fabspeed.

Note:

Only Fabspeed Motorsport USA uses Helical Limited England exhaust valves on all systems.

Porsche uses Helical exhaust valves on their GT3 mufflers because the valves are bullet-proof silica carbide.

FYI- Ferrari, Lamborghini, McLaren, Aston Martin all demand and use Helical exhaust valves UK for their cars because only Helical doesn't melt, crack, break, flutter or rattle.
