G20/G22/G26 304 Stainless Steel Valved Catback Exhuast for 330i/430i

The factory exhaust system on the B46/B48 platform is designed for comfort and emissions, limiting both exhaust flow and sound. This 304 stainless steel valved exhaust system improves exhaust flow, enhances throttle response, and delivers a deeper, more aggressive tone.

Available in both cat-back and axle-back configurations, you can choose the setup that best fits your goals. The cat-back offers a more complete upgrade in flow and sound, while the axle-back provides a simpler installation with a noticeable increase in exhaust tone.

With integrated valve control, you can switch between a quieter, refined sound for daily driving and a more aggressive tone when desired. The system is designed to maintain minimal drone while improving overall sound and response.
