BMW 4 Series G22 440i Coupe Rear Bumper Diffuser/Valance Insert – Gloss Piano Black ABS | M Performance MP Style Lower Trim, Square Exhaust Cutouts | CT Carbon OEM+ Rear Apron/Splitter | 2020+

Transform the rear end of your G22 440i with this CT Carbon rear valance in a deep high-shine black finish. Designed for the G22 chassis, this motorsport-inspired rear bumper lower trim gives your coupé a sharper, wider stance with precise square tailpipe apertures tailored to the 440i.

Crafted from durable ABS, the piece arrives pre-finished in a mirror-black look that complements factory paintwork and OE black pack details. It is a direct replacement style upgrade that integrates cleanly with the original rear bumper for a premium, OEM-plus appearance.
