BMW 8 Series G14 / G15 / G16 840i B58 3.0T SS304 Valved Catback Exhaust System

Upgrade your BMW 8 Series G14 / G15 / G16 840i B58 3.0T with a premium SS304 stainless steel valved catback exhaust system, designed to deliver a deeper, sportier and more aggressive exhaust character while maintaining convenient control over the sound level.

The integrated Valvetronic exhaust valve system is designed to work with OEM valve control functionality, allowing the exhaust valves to be adjusted according to the vehicle’s compatible factory control setup. This provides the flexibility to retain a more refined exhaust tone during everyday driving while unlocking a stronger and more performance-focused sound when desired.

Manufactured from SS304 stainless steel with 1.5 mm wall thickness, the system provides excellent durability, corrosion resistance and long-term performance. Mandrel-bent stainless steel tubing helps maintain smooth exhaust flow, while the vehicle-specific configuration is developed around the BMW B58 3.0T performance platform.

Designed as a performance-oriented catback upgrade, this exhaust system combines premium stainless steel construction, electronic valve functionality and a clean OEM+ appearance, making it an ideal upgrade for BMW 840i owners looking to improve sound, styling and the overall driving experience.
