Milltek Downpipes are the perfect solution when looking to improve both performance and sound. Milltek's downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency. Combined with a Milltek Hi-Flow Sports Cat, you can expect a significant increase in performance and a noticeable difference in sound.

About Milltek Sport


A product of the '80s, Milltek Sport was founded by a true car enthusiast looking to create incredible performance exhaust systems for a huge range of vehicles to distribute the world over - let's just say the company certainly hasn't disappointed. Over the past three decades, Milltek Sport's gifted team of engineers have developed and tested at the iconic Nürburgring in Germany using their in-house state-of-the-art CNC equipment and laser scanners. This has allowed the continual delivery of innovative exhausts designs, all of which are TUV approved and manufactured from highly durable T304L stainless steel so they'll last even in the toughest environments.
