Milltek Full Resonated Exhaust - Mini Cooper S R52 - Hi-Flow Sports Catalyst & Polished Tips - SSXM014

Milltek full resonated exhaust system for Mini Cooper S R52 (R50/R52 chassis). This complete turbo-back system replaces the OEM exhaust from the engine block to the tailpipes, engineered with our Hi-Flow sports catalyst for improved flow and engine efficiency without sacrificing the refined, resonated tone you expect on the street.

Constructed from T304L stainless steel with mandrel-bent piping and hand-finished tailpipe trims. The resonated design eliminates drone at cruise while preserving full-throttle character. Direct factory fitment using OEM hangers-no modification required. Dyno-proven to deliver measurable power gains over stock.

• T304L stainless steel mandrel-bent construction
• Hi-Flow sports catalyst reduces backpressure
• Resonated system for street-friendly tone
• Polished tailpipe trims
