The Milltek Sport Large-Bore Downpipe & Hi-Flow Sports Cat has been designed for the Mk3 Focus ST to improve exhaust gas flow, reduce back-pressure and enhance both performance and sound.

Featuring a large-bore design, the Milltek Sport downpipe provides significantly greater space for exhaust gases to exit the engine compared with the restrictive OE component. Combined with a high-flow sports catalyst, this improved gas flow increases exhaust efficiency and allows the turbocharger to operate more effectively.

Constructed from high-quality stainless steel, the Milltek Sport downpipe and Hi-Flow Sports Cat are designed to provide improved durability, performance and fitment. The high-flow catalyst also helps to maintain effective emissions control while offering a noticeable improvement in exhaust sound.

The downpipe and sports cat are designed to work alongside either the Milltek Sport or mountune cat-back exhaust system, providing improved exhaust flow throughout the system. This product is not compatible with the standard OE cat-back exhaust system. The mountune m300 calibration will need to be installed for this upgrade to work correctly and to prevent the EML (Engine Management Light) from being illuminated.
