Milltek Sport Audi RS4 B7 - Cat Replacement Pipes (SSXAU285)

The part is used to bypass the catalyst from the exhaust to create a ‘Decat’ system. Eliminating the catalyst will greatly enhance the gas-flow and the performance, adding significant Hp to your vehicle by removing the density of the catalyst in which exhaust gases are pushed through. - This product is intended for motorsport use only and requires Stage 2 ECU remap.

All our 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.
