Milltek Sport Large-Bore Downpipes are designed to enhance both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, providing increased space for exhaust gases to exit the engine and pass through, which improves efficiency. When used with the Catalyst Bypass Pipe, significant power gains can be achieved without restriction from a catalyst. All Milltek Sport performance exhaust systems are developed to meet a wide range of vehicle requirements, with ongoing research and development to deliver in-demand solutions.
