The BMW M5… The flagship M Saloon. This particular came to us looking for more power and a bit more bark. We opted for the Supersprint downpipes; supplied and fitted by ourselves. With the downpipes fitted, we set about data logging and testing the vehicle on the rolling road and put together a software package that delivered smooth power delivery than held fantastic torque throughout the rev range.
Upon completion, we managed to achieve a very impressive 740HP, an excellent 140HP increase over standard figures.
