Product Description

The Milltek Non-Resonated Catback Exhaust is engineered for Audi 8V.5 RS3 enthusiasts seeking a more engaging exhaust note without compromising fitment or build quality. Designed for the turbocharged 2.5 TFSI five-cylinder engine, this system enhances the RS3's distinctive exhaust character while providing a high-flow replacement for the factory exhaust.

The non-resonated configuration eliminates the additional front silencer, allowing a deeper, louder, and more pronounced exhaust note during acceleration. Its 3" mandrel-bent stainless steel tubing promotes efficient exhaust flow, making it a suitable upgrade for performance-focused street builds.

Manufactured from corrosion-resistant T304L stainless steel, the system features Milltek's HollowTek rear silencer and precision-engineered components for durability and consistent performance.

Designed and manufactured in the United Kingdom, the Milltek exhaust uses factory mounting locations for direct installation. The result is a premium catback system that combines distinctive five-cylinder sound, quality construction, and personalized styling.
