Valved Catback Exhaust for BMW 330i

This valved performance exhaust system allows you to switch anytime between a quiet daily driving tone and an aggressive performance sound. Built from high-grade 304 stainless steel with TIG welding for durability, clean welds, and long-term heat resistance. The system is fully bolt-on with no cutting or welding required, making installation simple at most shops. Engineered to improve exhaust flow and throttle response, it gives the M330i a deeper, sharper tone compared to the factory system—especially noticeable when the valve is open.

Fitment: Compatible with BMW 330i models (availability may vary by year and region). Supports factory mounting points and works with OEM valve wiring or a wireless valve controller depending on configuration.

What’s Included: Mid-pipe + rear valved catback system, mounting hardware and clamps, and a remote valve controller or OEM valve integration depending on setup.

Sound Characteristics:

• Cold Start: deep and sporty

• Valve Open: loud, aggressive tone with clean pops and performance character

• Valve Closed: close to OEM comfort for neighborhoods and daily driving

Shipping: Ships directly from our partner factory with an estimated delivery time of 2–5 weeks, depending on location and courier speed.

Warranty: If the exhaust arrives damaged or defective, replacement parts will be provided.
