Show original supplier description
The Kreissieg BEFS-03 is a premium cat-back valvetronic exhaust system engineered for the Bentley Flying Spur W12. This valvetronic exhaust system allows drivers to customize their vehicle's sound profile, choosing from multiple sound stages. Standard configurations include a "silent mode" at Level 2 for a sportier yet subdued tone, and an exhilarating "F1 Mode" up to Level 5, delivering a high-pitched and very loud F1-inspired sound. Customers can select their preferred sound level, with options ranging from stock sound levels to distinct F1 tones. Key specifications include dual 70mm valves and a wireless control switch for seamless operation. While offering a sophisticated sound experience, Kreissieg advises that due to the system's complexity, it is not recommended for race applications. Each Kreissieg exhaust system is meticulously handcrafted in Japan and built to order. Please allow 14-20 days for production after purchase. International air shipping via DHL Express is available, with shipping charges automatically calculated during checkout.
