Description

BMW M850i G14 / G15 / G16 N63 4.4T SS304 Valved Catback Exhaust System

Upgrade your BMW M850i G14 / G15 / G16 equipped with the N63 4.4T V8 engine with a premium SS304 stainless steel valved catback exhaust system, designed to deliver a deeper, more powerful and aggressive exhaust character while maintaining control over the sound level for everyday driving.

The integrated Valvetronic exhaust valve system allows the exhaust sound to be adjusted on demand, giving you the flexibility to enjoy a more refined and comfortable exhaust tone during normal driving and a stronger, more performance-focused V8 sound when the valves are opened.

Manufactured from premium SS304 stainless steel with 1.5 mm wall thickness, the system offers excellent durability, corrosion resistance and long-term performance under demanding driving conditions. Mandrel-bent stainless steel tubing helps maintain smooth exhaust flow, while the vehicle-specific configuration is designed around the BMW N63 4.4L Twin-Turbo V8 platform.

Designed as a complete 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 M850i owners looking to enhance sound, styling and the overall driving experience.
