Transform your 2020+ Mercedes-AMG GLS63 X167 with our GCA Performance Valved Sport Exhaust System, engineered to deliver an aggressive AMG sound, improved exhaust flow, and enhanced performance from the powerful 4.0L Twin Turbo V8 M177 engine.
Designed by German Car Accessories (GCA) under our performance division, this exhaust system replaces the factory setup with a lightweight, high-flow solution designed to reduce back pressure and optimize exhaust flow. The result is improved throttle response, stronger performance potential, and a more exciting V8 exhaust note.
Featuring electronically controlled exhaust valves, this system gives you complete control over your driving experience. Enjoy a refined and comfortable tone during daily driving, then open the valves for a deeper, more aggressive AMG sound when you push the throttle.
Manufactured from premium T304 stainless steel with optional titanium construction, this exhaust system is built for durability, heat resistance, and long-term performance. Precision TIG welding ensures exceptional strength and perfect fitment.
