Transform the sound and performance of your 2019+ BMW Z4 with the GCA Performance Valved Sport Exhaust System. Designed specifically for the G29 platform, this premium cat-back exhaust delivers improved exhaust flow, sharper throttle response, and an aggressive exhaust note while giving you complete control over the sound with electronically controlled exhaust valves.
Developed in-house by German Car Accessories under our GCA Performance line, this exhaust system is available in high-quality T304 stainless steel or 6AL-4V Grade 5 titanium for exceptional durability, corrosion resistance, and reduced weight. The mandrel-bent tubing minimizes exhaust restriction and back pressure, allowing the turbocharged B48 and B58 engines to breathe more efficiently for improved horsepower, torque, and turbo response.
With the included electronic valve controller, you can enjoy a refined, quiet exhaust during daily driving or instantly switch to a deep, aggressive performance tone whenever you want. Designed as a direct bolt-on replacement, this system installs using factory mounting locations with no permanent modifications required.
