More than 10kg of weight reduction over OEM components and still maintaining required strenght and stiffness

The increased flow is achieved through the efficiency of a straight-through valve versus a traditional poppet-style valve where the exhaust gas must be turned 90 degrees by the valve

This is particularly beneficial if you want to keep the car in streetable condition or if you prefer to avoid excessive overfenders

There are no springs
