BMW X3M / X4M FULL EXHAUST (S58) F97/F98
Welcome to S58 glory! With the introduction of the new TwinTurbo 3L inline-six from BMW, we worried that this engine will have the same problem as the F8X cars. Fortunately it out of the box the systems have a much more raw and less raspy sound than the F8x cars. But as always with this new generation of cars and regulations, they leave a lot to be desired in regards to sound quality and volume. Our goal for the S58 platform was to accentuate the already good sounding engine note and refine some of the raspy tones that come out of these cars. Slightly larger piping and use of 2 center resonators help provide an even and smooth tone throughout the rev range. This system is also significantly lighter than the OEM setup and reuses the OEM electronic Valves for easy integration with the Sport and Sport + modes.
