MillTek Audi RS5 Sport Cat (2019-2021)



Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These 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.

Milltek Sport's range of Cast Downpipes offer further enhancements to gas-flow and heat management, being designed to increase efficiency and performance gains. The HJS High-Flow Sport Catalyst is the highest quality and best performing aftermarket Catalyst. The quality of the product is made to reduce the density of OEM Catalysts and be able to maintain emission regulations with daily usage. Standard OEM Catalysts are usually 500-600 cells, our high flow Catalyst reduces this to 200 cells. This makes the Catalyst freer-flowing, improving gas-flow and performance. Milltek Sport are the sole UK distributor of HJS Tuning Catalysts. All performance exhaust systems are designed with you in mind, and we Cater to an ever-expanding range of vehicles. We believe in continuous evolution, and our research & development team work throughout the year to deliver the most in demand solutions to all your performance exhaust requirements. All of our products are made in the UK and distributed to more than 90 countries worldwide, making Milltek Sport one of the most accessible performance aftermarket brands on the market.
