Milltek Non-Resonated Cat-Back Exhaust - Mini F66 Cooper - Carbon Fibre Tips - SSXM496

Milltek Non-Resonated Cat-Back Exhaust System for 2-Door Mini F66 Cooper. Direct replacement for factory exhaust with OPF/GPF compatibility. 3" (76.2mm) mandrel-bent T304L stainless steel construction with hand-finished carbon fiber tip option.
