Helical Valves:
Fabspeed's Side Muffler Bypass Pipes incorporate Helical Valves, known for their exceptional quality and precision. These valves are used by top manufacturers like McLaren, Ferrari, Lamborghini, and Pagani. Helical's design includes durable pneumatic actuators, precision flat sealing faces, stiffening ribs, and high-temperature bearings, ensuring optimal gas flow and engine back-pressure for improved performance. Fabspeed Motorsport USA is the exclusive importer of these valves.
O2 Bungs:
The design relocates O2 bungs from the headers' collector to the Side Muffler Bypass Pipes, maintaining factory-like functionality with Long Tube Competition Race Headers. This setup allows oxygen sensors to read all cylinders, maximizing collector performance and offering additional ports for data acquisition.
Note: Fabspeed Motorsport USA exclusively uses Helical Limited England exhaust valves. Porsche, Ferrari, Lamborghini, McLaren, and Aston Martin rely on these valves for their sports and hypercars due to their unmatched durability and performance.
