The Milltek Sport Large Bore Downpipe with Catalyst Delete for the Mini Cooper F56 (Pre-LCI 2014-2018) is engineered for drivers seeking maximum performance and improved exhaust flow. Featuring a significantly larger diameter than the OEM downpipe, this system reduces back pressure and allows exhaust gases to exit more efficiently. Unlocking noticeable power gains when paired with a suitable ECU tune.
Designed specifically for use with the original OE Cat-Back exhaust system, this downpipe is ideal for track-focused builds where performance takes priority over emissions compliance.
