The 3D Design G8X M3 / M4 Valved Rear Exhaust is a performance rear muffler system engineered for the G80 / G81 M3 and G82 / G83 M4, delivering a fully valve-controlled exhaust experience with a four-tip, 105mm exit layout. Developed specifically for the S58 powerplant, the system is JARI-certified for road legality in Japan and provides a substantial acoustic and visual upgrade over the factory setup while remaining appropriate for street-driven vehicles.
The exhaust system is constructed from a stainless steel exhaust system architecture with carbon fiber exhaust tips, combining the corrosion resistance and durability of stainless construction with the premium visual finish of carbon fiber outlets. The integrated valve mechanism preserves factory exhaust valve control through the OEM comfort and sport modes, while the 105mm quad-tip layout provides a visually assertive rear presentation that complements the aggressive G8X rear diffuser area.
Designed and manufactured in Japan, 3D Design components are developed with a focus on fitment precision, durability, and real-world usability. Their approach blends motorsport influence with street functionality, resulting in performance exhaust systems that enhance both acoustic experience and visual presence without sacrificing daily drivability.
