Description
Transform the presence, sound, and driving experience of your Mercedes-Benz G63 AMG or G550 (W463A/W464) with the Yonristic Performance Valved Side-Exit Exhaust System. Engineered specifically for the latest-generation G-Class, this premium exhaust system delivers an unmistakable AMG V8 soundtrack, improved exhaust flow, and an aggressive side-exit appearance while maintaining full factory valve functionality.
The factory exhaust system prioritizes refinement and global noise regulations, limiting the true character of the twin-turbocharged V8. Yonristic completely reimagines the G-Class exhaust with a high-flow architecture and an exclusive triple side-exit tip design, creating a bold visual statement while allowing the M177 and M176 V8 engines to produce the deep, commanding tone they deserve.
At the core of the system is a high-flow dual exhaust architecture that minimizes restriction through the cat-back section, improving exhaust gas evacuation and reducing backpressure. This supports faster turbo response, improved throttle sensitivity, stronger mid-range acceleration, and a richer V8 exhaust note without compromising everyday drivability.
The signature triple side-exit configuration features three precision-aligned outlets on each side, inspired by AMG motorsport heritage while adding a modern, aggressive appearance unique to the Yonristic design. Carefully engineered chambered mufflers balance performance with comfort, eliminating excessive drone while preserving the deep, muscular sound expected from the G-Class platform.
Electronically controlled dual valved mufflers integrate directly with the factory Mercedes-AMG valve control system. The exhaust retains the OEM valve actuators, wiring, and drive mode functionality, allowing seamless operation through the vehicle's original drive modes without additional controllers or modifications.
Constructed from premium AISI 304 stainless steel or optional Ti-6Al-4V Grade 5 titanium, every exhaust system is precision-formed, mandrel-bent, CNC-machined, and hand TIG-welded to ensure exceptional durability, corrosion resistance, lightweight performance, and OEM-quality fitment. The titanium version significantly reduces weight while producing a sharper, higher-pitched motorsport-inspired exhaust tone with an eye-catching heat-treated finish.
Designed around factory mounting locations, the system installs as a complete bolt-on upgrade using the supplied brackets and hardware, requiring no cutting, welding, or permanent vehicle modification.
