Valved Catback Exhaust for Mercedes-Benz GLS450

This valved exhaust system lets you switch freely between quiet daily mode and an aggressive performance tone. Built from high-grade 304 stainless steel with TIG welding for durability and clean finishing. Fully bolt-on installation — no cutting or welding required. Designed to improve airflow, enhance throttle response, and provide a deeper tone compared to stock, especially when the valve is open.
