BMW 330e Hybrid

Service Completed: Rear Section Backbox Delete & Quad Tip Upgrade

This BMW 330e Hybrid came in for a rear-section transformation, opting for a crisp and purposeful backbox delete upgrade.
We crafted a custom rear system that removes the restrictive factory box, opening up the tone while maintaining a clean, refined sound suited to the hybrid platform.

To complete the look, the setup was finished with aggressive quad matte-black tips, perfectly aligned to the upgraded diffuser/rear valance.
A sharp visual and acoustic enhancement that gives the 330e the presence it deserves.

Note: We don’t supply rear diffusers or valances, but we’re happy to fit them free of charge in most cases.
