Milltek Large Bore Downpipe with Hi-Flow Sports Catalyst for Mini Cooper S F55/F56. Direct fitment designed exclusively for use with Milltek Cat-Back exhaust systems. Mandrel-bent T304L stainless steel construction increases diameter beyond OEM specification, allowing greater exhaust gas flow and reducing backpressure for measurable performance gains.
The integrated Hi-Flow Sports Cat combines secondary catalyst efficiency with acoustic tuning. Stage 2 ECU remap required to unlock full potential. Hand-finished construction ensures OEM+ fitment using factory hanger points—no modifications necessary. Engineered for closed-circuit performance use.
