The Milltek Sport Large-Bore Downpipe with Catalyst Delete for the Mini Cooper S F55/F56 is designed for maximum exhaust flow, performance gains, and motorsport applications.
Fabricated with a larger diameter than standard OEM parts, this downpipe provides significantly more space for exhaust gases to exit the engine efficiently. When combined with the Catalyst Bypass Pipe, it delivers power gains without the restrictions of a catalytic converter, making it ideal for track use.
This product is intended for motorsport use only and requires a Stage 2 ECU remap to achieve optimal performance.
