Overview

The Milltek Sport SSXAU958 is a cat-back exhaust system designed for the Audi R8 V10 5.2L Gen 2. This system features 80mm (3.15-inch) non-resonated pipework for a louder, sportier tone.

Constructed from aerospace-grade 304L stainless steel, this exhaust is built for durability and resistance to discolouration. Milltek employs mandrel bending for optimized gasflow and carefully enlarges bore diameters to enhance performance without sacrificing mid-range torque. The exhaust undergoes rigorous acoustic development to achieve a crisp, sporty sound profile while preventing NVH, drone, or cabin resonance.
Show original supplier description
The Milltek Sport SSXAU958 is a premium cat-back exhaust system engineered for the Audi R8 V10 5.2L Gen 2 (OPF/GPF Equipped Models Only), specifically for the 2020 model year and later. Crafted from aerospace-grade 304L, non-magnetic stainless steel, this system is built to withstand harsh conditions and resist discolouration, ensuring longevity. Milltek utilizes mandrel bending techniques to maintain a constant radius in the pipework, optimizing gas flow for improved performance. The bore diameters are intentionally enlarged over stock specifications to maximize power output without compromising low-end torque. The system fits to OE trims and utilizes 80mm (3.15-inch) diameter piping. Milltek exhaust systems undergo extensive acoustic development to produce a sporty and crisp tone, while actively avoiding NVH, drone, and cabin resonance, ensuring a refined driving experience. It is important to note that the use of de-cats or sports cats are intended for off-road or motorsport use only and would prevent the vehicle from passing a MOT test. Only EC type-approved components are legal and fit for road use.
