Show original supplier description

The Milltek Cat-Back Exhaust System (SSXM012) is engineered for the Mini R50/R52, offering a blend of performance enhancement and lasting quality. Crafted from aerospace-grade Type 304 stainless steel, known for its non-magnetic properties and resistance to discoloration, this system ensures longevity and a premium appearance. The system's construction includes mandrel-bent 53.98mm (2.13-inch) pipework. This manufacturing process guarantees consistent bends and optimized gas flow, contributing to an increase in power by an estimated 10-12%. The bore diameters are enlarged over stock specifications to maximize performance without sacrificing mid-range torque. The system is finished with a single 90mm Jet polished tip. Milltek exhaust systems undergo a rigorous acoustic development process to achieve a sporty and crisp tone, while actively preventing NVH, drone, or cabin resonance. For convertible models, spacers may be required for undercarriage bracing, or the exhaust pipe may need to be bent at the mid-section for proper fitment. This cat-back exhaust system is designed as a direct factory fitment for the following vehicles: * MINI Cooper Convertible R52 (2005-2008) Base 1.6L * MINI Cooper Hatchback R50/R53 (2002-2006) Base 1.6L
