3DDesign Valved Rear Exhaust Section w/ Carbon Tips for G8x BMW M3 and M4 [4101-38211C]

RAYS’ 3DDesign Valved Rear Exhaust Section with Carbon Tips for the G8x BMW M3 / M4 is a high‑performance, motor-sport inspired rear tailpipe upgrade that delivers both aesthetic and acoustic enhancement. Designed for a perfect fit on the 2021+ G80 / G81 M3 and G82 M4 platforms, this valved exhaust section integrates carbon fiber quad tips, stainless piping, and an electronic actuator to provide switchable sound character — from refined to aggressive — while preserving factory drone control and OEM-like installation. Whether cruising or driving hard, it balances functionality, style, and dynamic presence.

The System

• 3DDesign’s exhaust systems are engineered to deliver smooth, responsive performance throughout the entire RPM range, with a focus on achieving the ideal balance of sound, feel, and quality. Developed in close collaboration with Arqray — renowned for their expertise in BMW-specific exhaust engineering — each system reflects a uniquely 3DDesign approach. These are not rebranded Arqray products; they are purpose-built systems developed from the ground up to meet 3DDesign’s distinct acoustic and design standards.

Control Valve

• The integrated control valve system, designed by 3DDesign, minimizes low-frequency resonance (drone) while enhancing torque delivery at lower RPMs. This advanced feature improves overall exhaust efficiency and adds a new layer of dynamic response to the driving experience.

Finish

• Exceptional attention was given to visual refinement, particularly in the detailing of the canisters and tips. Each component is carefully finished, engraved, and pressed with the 3DDesign logo by Arqray Co. to ensure a premium appearance.

Match the Diffuser

• Every exhaust is developed with the full vehicle aesthetic in mind. Designed to integrate seamlessly, 3DDesign’s diffusers pair perfectly with its exhaust systems, ensuring no fitment issues or visual mismatch.
