{"product_id":"titanium-stainless-steel-sport-exhaust-system","title":"Titanium \u0026 Stainless Steel Sport Exhaust System","description":"The QuickSilver RS378S is an active valve sport exhaust system precision-engineered for the Rolls-Royce Cullinan (2025 and newer). The system replaces the stock exhaust with a titanium silencer and 3-inch stainless steel tubing, resulting in a weight reduction of 5.5 kg compared to the factory unit. By integrating a titanium silencer, the system produces a warm resonance and enhanced dynamic range that emphasizes the Cullinan's V12 engine note.\n\nEquipped with Sound Architect active valve technology, the exhaust provides two distinct sound profiles: 'Sport' for a robust, aggressive tone and 'Refined' for a civilized, quieter experience. These valves can be controlled independently using the provided standalone key fob, offering the driver full command of the exhaust volume at any time.\n\nInstallation is designed for simplicity, utilizing a plug-and-play 12v power source in the vehicle's boot area. The system retains the original factory tips to maintain a stealthy aesthetic while providing a significantly more dynamic soundtrack throughout the rev range. The package includes the sound module, two key fobs, and all necessary wiring for a complete bolt-on solution.","brand":"QuickSilver","offers":[{"title":"Default Title","offer_id":52689349968184,"sku":"RS378S","price":5994.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687495161.jpg?v=1784905523","url":"https:\/\/store.motormia.co\/products\/titanium-stainless-steel-sport-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
