Valved Catback Exhaust for BMW 440i

This valved performance exhaust system allows you to switch between quiet OEM comfort and an aggressive performance tone anytime. Built using high-grade 304 stainless steel with TIG welding for clean finish, strength, and long-term durability. Fully bolt-on installation — no cutting or welding required. Engineered to improve exhaust flow, enhance throttle response, and provide a deeper, sharper sound compared to stock when the valve is open, while keeping the car quiet and daily-friendly when closed.

Fitment: Compatible with BMW 440i (coupe, sedan, or convertible depending on configuration). Fits factory mounting points and supports OEM valve wiring or remote valve control depending on setup.

What’s Included: Mid-pipe + rear section with valve system, mounting hardware and clamps, and either a remote valve controller or OEM valve integration depending on the configuration.

• Cold Start — deep and noticeable tone

• Valve Open — aggressive, sporty, and performance-focused with clean pops

• Valve Closed — close to OEM comfort suitable for daily use
