The FJ MotorWerkes G90/G99 Midpipe has been developed specifically for enthusiasts looking to transform the sound and performance characteristics of the all-new BMW M5 G90 Saloon and G99 Touring. Featuring a precision-engineered equal-length xpipe design, this system balances exhaust flow across both turbo banks to deliver deeper and sportier tone.

Available in both Resonated and Non-Resonated configurations, the system is designed to suit drivers wanting either a refined, deep tone or a louder, aggressive motorsport-inspired sound profile.

Manufactured using high-grade mandrel-bent T304 stainless steel,
