Unlock the full performance potential of your BMW G80 M3, G82 M4 Coupe, or G83 M4 Convertible with the German Car Accessories M Performance Style Valved Sport Exhaust System. Developed under the GCA Performance lineup, this premium cat-back exhaust system is engineered specifically for the 3.0L Twin Turbo S58 engine, delivering a deeper exhaust tone, improved throttle response, enhanced airflow, and an aggressive motorsport-inspired presence.
Designed for BMW models already equipped with the factory M Performance Exhaust or M Performance Diffuser, this exhaust system provides a seamless upgrade for enthusiasts looking to enhance the sound and appearance of their G8X M3/M4. Vehicles with the standard factory exhaust setup should use the alternative GCA valved exhaust system designed for standard configurations.
The electronically controlled exhaust valves allow complete control over your exhaust sound. Keep the vehicle refined and comfortable during daily driving, or open the valves to experience a deeper, more aggressive exhaust note during spirited driving — all controlled with the included valve controller.
Manufactured from high-quality T304 stainless steel or 6AL-4V Grade 5 titanium, this exhaust system combines exceptional durability, lightweight performance, and resistance against high temperatures and corrosion. The complete cat-back system includes a 3.5-inch single equal-length mid-pipe designed to improve exhaust flow and enhance the S58 engine's sound characteristics.
Finished with premium quad exhaust tips available in chrome, blue titanium, gloss black, or carbon fiber options, this exhaust system adds a race-inspired appearance while maintaining an OEM+ fit and finish.
German Car Accessories proudly stands behind every GCA Performance product, and this exhaust system is backed by a 1-Year Warranty.
