The Milltek Sport Large-Bore Downpipe with Hi-Flow Sports Catalyst for the Mini Cooper S R56/R58 is engineered for drivers seeking maximum performance gains, improved exhaust flow, and enhanced sound quality.
Manufactured with a larger diameter than OEM downpipes, this system allows more exhaust gas to exit the engine efficiently, increasing performance. Combined with the included Hi-Flow Sports Catalyst, this system improves gas flow while maintaining road-legal emissions, resulting in a noticeable increase in power and a richer exhaust tone.
This product is designed for track and road use and must be paired with a Stage 2 ECU remap for optimal performance. Fitment requires a Milltek Cat-Back exhaust system.
