Valved Catback Exhaust for BMW 540i (G30) (2017–2023)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style refinement and a louder, deeper, more aggressive performance tone. Built from high-grade 304 stainless steel with precision TIG welding, it offers excellent durability, corrosion resistance, and a clean premium finish. The system is fully bolt-on — no cutting or welding required — making installation straightforward for most professional exhaust shops. Designed specifically for the B58 turbocharged inline-6 engine in the G30 540i, it improves exhaust flow and throttle response while delivering a sharper, fuller, and more dynamic exhaust note when the valve is open, yet maintaining smooth daily-driving comfort when closed.

Fitment: Compatible with BMW 540i (G30, 2017–2023) including RWD and xDrive variants equipped with the 3.0L B58 turbo inline-6. Fitment can be confirmed using VIN or a rear exhaust photo.
