Unlock the full sound and performance potential of your BMW’s Twin-Turbo V8 with the GCA Performance Valved Sport Exhaust System, engineered specifically for 2018–2023 BMW M550i, M550i xDrive, and Alpina B5 models equipped with the 4.4L Twin-Turbocharged N63 engine.
Designed by German Car Accessories under the GCA Performance line, this premium cat-back exhaust system delivers a more aggressive exhaust note, improved exhaust flow, and enhanced driving engagement while maintaining everyday drivability. Whether cruising comfortably or pushing the limits of your V8-powered BMW, the integrated electronic valve system allows you to control the exhaust sound on demand.
Constructed from high-quality T304 stainless steel or optional 6AL-4V Grade 5 titanium, this exhaust system combines exceptional durability with lightweight performance. Precision TIG welding ensures maximum strength, consistent quality, and OEM-level fitment throughout the entire system.
The free-flowing design helps reduce exhaust restriction and back pressure, allowing the N63 engine to breathe more efficiently. The result is improved throttle response, enhanced exhaust tone, and the potential for increased horsepower and torque when paired with supporting modifications.
Featuring a complete cat-back configuration, the system includes both the mid-pipe and axle-back sections, along with quad exhaust tips for a bold performance appearance. The fully reversible design allows the vehicle to be returned to stock configuration at any time without permanent modifications.
Backed by a 1-Year Warranty and engineered specifically for the G30 platform, this valved exhaust system delivers premium sound, performance, and craftsmanship for enthusiasts seeking the ultimate V8 driving experience.
