Valved Catback Exhaust for BMW X3 35i (F25) (2011–2017)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style comfort and a louder, deeper, more aggressive turbocharged tone. Constructed from high-grade 304 stainless steel with precision TIG welding, it provides excellent durability, corrosion resistance, and a clean factory-style finish. The system is fully bolt-on — no cutting or welding required — making installation easy for most exhaust shops. Designed specifically for the N55 turbo inline-6 engine in the F25 X3 35i, it improves exhaust flow and throttle response while delivering a fuller, sharper, and more dynamic sound when the valve is open, while keeping OEM-level refinement when closed.

Fitment: Compatible with BMW X3 35i (F25, 2011–2017), Fitment can be confirmed using VIN or a rear exhaust photo.
