Milltek Non-Resonated Cat-Back Exhaust - Mini F66 Cooper S - Burnt Titanium Tips - SSXM495

The Milltek Non-Resonated Cat-Back System is engineered for the F66 Mini Cooper S, delivering enhanced exhaust flow and an aggressive, track-focused sound character. This system replaces the factory OPF/GPF-back setup and requires fitment with the supplied Milltek Design Diffuser overlay (cutting required for installation).

Constructed from T304L stainless steel with hand-finished Burnt/Blue Titanium tips, the system features a large-bore 3" (76.2mm) mandrel-bent pipe diameter for improved scavenging and reduced back-pressure. The non-resonated design eliminates OE silencing, producing a full-throttle character suited for closed-course and track driving. Direct OEM hanger compatibility ensures OEM+ fitment accuracy.
