Overview

The Milltek Sport SSXAU534 is a cat-back exhaust system featuring non-resonated, louder performance with quad round titanium tips. This system is crafted from aerospace-grade type 304 non-magnetic stainless steel, offering superior durability and resistance to discolouration.

The system is designed with mandrel-bent tubing for optimized gas flow and enlarged bore diameters over stock to enhance performance without sacrificing mid-range torque. Milltek's acoustic development process ensures a sporty and crisp exhaust tone that avoids NVH, drone, or cabin resonance. It is exclusively for non-GPF equipped models from 2013-2018.
Show original supplier description
The Milltek Sport SSXAU534 is a premium cat-back exhaust system engineered for enhanced performance and an aggressive sound profile. This system features a non-resonated design for a louder, sportier tone and is finished with striking quad round titanium tips. Constructed from aerospace-grade type 304 non-magnetic stainless steel, the exhaust is built for exceptional longevity and resistance to discoloration. Milltek's commitment to performance is evident in the SSXAU534's construction. Mandrel bending ensures consistent radius bends for optimal gas flow, while enlarged bore diameters over stock contribute to increased performance. The system has undergone a comprehensive acoustic development process to deliver a sporty and crisp exhaust note without introducing undesirable NVH, drone, or cabin resonance. This exhaust is designed as a direct replacement for the original system, aiming for a straightforward installation. This particular Milltek Sport cat-back exhaust system is specifically designed for Audi S3 2.0 TFSI quattro Sportback models (8V/8V.2) from 2013 to 2018. It is crucial to note that this system is exclusively for models equipped without a gasoline particulate filter (non-GPF). The use of de-cats and sports cats, if included in related products, are intended for off-road or motorsport use only and may render the vehicle ineligible for MOT testing. Only EC type-approved components are legal for road use.
