Same part# same bullet proof quality. which have been 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 Ultra high temperature high-temperature bearings at both ends of the butterfly spindle. Helical is an Aerospace Company that also makes exhaust components.
