BMW G90 / G99 M5 VANTA GOLD Exhaust System

Yonristic Performance

The VANTA GOLD Exhaust System for the BMW G90 and G99 M5 represents the latest evolution of Yonristic Performance exhaust engineering for the new-generation M platform. Built around a dual 3-inch midpipe architecture paired with the proprietary AURUM FLOW CORE™, the system is designed to unlock the true character of the S68 twin-turbo V8. Inspired by our VANTA Edition design philosophy, VANTA GOLD delivers a deep, aggressive European V8 tone while maintaining the composure, refinement, and usability expected from a modern flagship M car.

The VANTA GOLD Exhaust System for the BMW G90 and G99 M5 represents the latest evolution of Yonristic Performance’s advanced exhaust architecture. Developed specifically for the new-generation M5 platform, the system features a dual 3-inch midpipe layout paired with the proprietary AURUM FLOW CORE™, creating a center section engineered to stabilize exhaust pulses while maintaining high flow efficiency. This configuration allows the V8 powerplant to breathe more freely, improving exhaust velocity and reducing restriction across the system.

From an acoustic standpoint, VANTA GOLD transforms the character of the M5 with a clean, aggressive European V8 tone. The sound remains deep and composed at low RPM while building into a sharp, exotic upper-range note as the engine revs. The AURUM FLOW CORE™ plays a central role in this behavior, guiding exhaust pulses through sculpted internal flow paths that tighten the sound signature and prevent the harsh breakup or rasp often associated with traditional crossover designs. The result is a powerful yet controlled sound profile that complements the performance nature of the M5.

The system’s dual 3-inch midpipe architecture maximizes airflow while preserving harmonic balance between the two banks of the engine. This improved flow efficiency contributes to measurable gains in both horsepower and torque, allowing the engine to respond more freely under load. As with other VANTA GOLD systems, the exhaust retains valve integration for everyday drivability while unlocking a far more dynamic sound when fully opened.

Production of the VANTA GOLD series for the G90 / G99 M5 is extremely limited, due in part to the complex manufacturing process of the AURUM FLOW CORE™ and the time required for precision finishing. Each system is produced in limited batches, prioritizing quality and consistency over volume.

For customers seeking additional performance, Yonristic Performance also offers high-flow downpipes with integrated heat shields, designed to further reduce restriction and unlock additional power potential when combined with appropriate calibration.

The result is a complete exhaust solution designed to enhance the sound, performance, and character of the new BMW M5.

Sound Character – S68 V8

The S68 V8 delivers immense power, but its factory exhaust system prioritizes compliance and refinement over character. VANTA GOLD is engineered to restore the natural personality of the engine while maintaining control across the entire rev range.

At low engine speeds, the exhaust produces a deep and authoritative V8 tone that reflects the displacement and strength of the engine. As the revs climb, the sound transitions into a clean, aggressive mid-range before opening into a sharp, exotic upper-RPM note that remains composed under load. The AURUM FLOW CORE™ plays a central role in this behavior by aligning exhaust pulses through sculpted internal flow channels rather than allowing chaotic gas collision.

This controlled pulse management tightens the exhaust note and prevents the harsh rasp or frequency breakup often heard in traditional crossover designs. The result is a sound that remains structured, aggressive, and unmistakably European, delivering a level of tonal discipline rarely achieved in high-output turbocharged V8 platforms.

When the valves are closed, the system maintains the refinement expected of a modern luxury performance sedan or wagon. When opened, the exhaust reveals the full VANTA GOLD character—powerful, precise, and unmistakably performance-oriented.

Performance Gains

By improving exhaust flow and reducing restriction, the VANTA GOLD system allows the S68 V8 to operate more efficiently while improving throttle response.

Estimated Gains (Cat-Back Only)

Horsepower: +15 – 25 HP
Torque: +20 – 35 lb-ft

For customers seeking maximum output potential, the system can be paired with Yonristic Performance high-flow downpipes with integrated heat shields (track use only). When combined with proper ECU calibration, significantly higher gains can be achieved depending on supporting modifications and fuel selection.
