I recently received and installed mine. It sounds amazing, imho its the best exhaust for a 335 n54. Id say its better than the vrsf race because it fits xdrive 335s and it has a resonator to curb rasp and drone. Budget Bimmers made a vid of them adding a resonator to the vrsf race exhaust which is exactly how the ATM exhaust comes.
