Large Bore Downpipe / Hi-Flow Sports Cat [Mk4 Focus ST]

The Milltek Sport Large-Bore Downpipe & Hi-Flow Sports Cat has been designed for the Mk4 Focus ST to improve exhaust gas flow, reduce back-pressure and enhance both performance and sound.

Featuring a large-bore design, the 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.

This downpipe and sports cat is required for the mountune m365 calibration and is also compatible with the mountune m330 calibration, making it an ideal upgrade for customers looking to improve exhaust flow and support increased performance.
