BMW G20 3 Series 330i 330e M340i M Sport VT Style LED Rear Diffuser Kit with Carbon Fiber Quad Exhaust Tips 2019-2022

Upgrade the rear-end appearance of your 2019-2022 BMW G20 3 Series with this VT Style LED Rear Bumper Diffuser Kit and Carbon Fiber Quad Exhaust Tips. Designed specifically for compatible M Sport rear bumpers, this complete five-piece exterior upgrade combines an aggressive shark-fin diffuser, matching corner extensions, and a quad exhaust tip setup for a bold, performance-inspired appearance.

The VT Style diffuser is constructed from durable, lightweight polypropylene (PP) with a painted gloss black finish. Its large shark-fin design and integrated vertical LED third brake light create a distinctive motorsport-inspired rear profile. Matching left and right corner extensions complete the lower bumper styling, giving the vehicle a wider, more aggressive appearance.

The kit also includes polished stainless steel quad exhaust finishers surrounded by genuine glossy carbon fiber with UV protection. These tips feature integrated venting and drainage holes for heat and moisture management. The M340i exhaust tip setup is designed for direct bolt-on replacement, while 330i and 330e models require cutting and modification of the original exhaust system. Electrical wiring and splicing are required for the LED brake light, and professional installation is strongly recommended.
