Bmw X3M X4M S58 Premium Titanium Equal length Catback Exhaust System Pre lci + Lci

At FJ MotorWerkes, our Titanium Grade 5 Full Catback Exhaust System is precision-engineered to completely transform both the performance and sound of your BMW M platform. Designed as a full replacement from the mid-section back, this system integrates seamlessly with OEM mounting points while delivering a true motorsport-inspired upgrade.

The S58 twin-turbo engine’s factory exhaust design can produce an uneven, restricted sound profile. Our full catback system utilises an equalised flow design to eliminate harsh rasp and unlock a deep, aggressive tone, giving your M car the refined yet commanding presence it deserves.

Constructed from premium Grade 5 titanium, this system offers an exceptional strength-to-weight ratio, significant weight reduction over stock, and superior heat resistance, ensuring long-term durability under high-performance conditions.
