The Milltek Sport Large-Bore Downpipe with Hi-Flow Sports Catalyst for the Mini Cooper S F55/F56 is engineered to maximize exhaust flow, performance, and sound quality.
 
Constructed with a larger diameter than standard OEM downpipes, this system provides significantly more space for exhaust gases to exit the engine efficiently. When combined with the included Hi-Flow Sports Catalyst, you can expect noticeable performance gains and a richer, more aggressive exhaust tone while maintaining compatibility with your OE Cat-Back system.
 
This product is intended for use on track or road with a Stage 2 ECU remap for optimal performance.
