The BMW S63R 4.4l Twin Turbo V8 engine is tuned to 575 Hp, stock; however it has a huge potential for more torque and more peak hp.
The Supersprint headers use the same pattern as the stock exhaust manifold, which merges the primaries in pairs (based upon the specific firing pattern of the 8 cylinders), running from the head, opposite exhaust ports down to each of the inlets of the twin scroll turbo chargers.
The round section, tubular design of the eight primaries eliminates all of the restrictions, while the precision crafted, merge connections optimize the energy of the hot exhaust gas charge into the turbos, transforming the improved spooling efficiency into increased boost pressure of the intake air charge, at all rpm.
The special, steel alloy of the Supersprint headers is the exclusive 310S grade, which had been developed and used successfully on F1, race headers applications.
The proprietary tubing material and the design of the Supersprint own expansion joints / sealing rings ensures a leak-free operation, an optimum resistance to the extreme temperature of the exhaust gas, and a service-free, long life of the headers.
