Show original supplier description
The Milltek Sport SSXAU285 is a 2.5-inch cat replacement pipe assembly designed for performance enhancement. The pipework features mandrel bends, ensuring constant radius bends for optimized gas flow and improved performance. Bore diameters are enlarged over stock to maximize ultimate performance potential without sacrificing mid-range torque. This cat replacement pipe assembly is specifically designed to be fitted with the Milltek Sport cat-back system and necessitates a Stage 2 ECU remap for optimal function. It is intended for use on the Audi RS4 B7 4.2 V8 Saloon, Avant, and Cabriolet models from 2006 to 2008. Please note that the use of de-cats and sports cats is generally for off-road or motorsport use only, and may inhibit a vehicle from passing a MOT test. Only EC type-approved components are legal and fit for road use.
