Welcome to a very vital sound and performance upgrade for the Alpina B8. From factor in this car is lacks the aggressive sound and presence that many owners desire. At Valvetronic Designs we have engineered a bespoke system for this platform that takes the enjoyment level up a few notches, adds power and a very enjoyable sound experience. This full system bolts up to OEM downpipes or can be combined with a free flow front race pipe setup. Valves are controlled via the OEM sport and sport plus buttons inside the vehicle. This system is a direct replacement for the factory OEM exhaust and is guaranteed to add power and a delicious sound through the rev range. At Valvetronic Designs, we do not compromise. Neither should you.
