Milltek Non-Resonated GPF-Back Exhaust - Mini F66 JCW - Cerakote Black Tips - SSXM511

Milltek Non-Resonated Gasoline Particulate Filter-back exhaust system for Mini F66 JCW (late 2018+). Engineered to restore the authentic exhaust character lost through OPF emission control, this T304L stainless steel system features mandrel-bent construction and CNC-formed Cerakote Black tips for direct factory fitment without modification.

Hand-finished throughout. The non-resonated design delivers unfiltered full-throttle tone and optimized backpressure tuning at the OE resonance point. GPF-back configuration means the particulate filter remains in the factory location-no secondary cat removal. Dyno-tested for peak performance gains while maintaining OEM valve compatibility.

• T304L stainless steel, mandrel-bent throughout
• Cerakote Black polished tips
• Direct factory fitment, uses OEM hangers
• Non-resonated system-closed-course and track use
