Audi S3 2019

Service Completed: Custom Valved Rear Exhaust Upgrade

At MIJ Exhaust Ltd, we recently completed a bespoke rear exhaust upgrade on this Audi S3 Sportback 2.0L Petrol (2019), enhancing both the sound and versatility of the vehicle.

This build featured a custom valved rear section, allowing the driver to switch between a refined, understated tone and a much more aggressive, performance-focused exhaust note on demand. With the valves closed, the system retains a smooth, OEM-style sound ideal for daily driving. Open the valves, and the S3 delivers a deeper, sharper tone with increased presence, perfectly matching its sporty character.

The upgraded rear section also improves exhaust flow, helping the engine perform more efficiently while adding to the overall driving experience.

Designed to integrate seamlessly with the vehicle, the system maintains a clean OEM+ appearance while subtly elevating the rear-end styling.

As with all of our exhaust systems, this setup was hand-fabricated in-house using high-quality T304 stainless steel and fully TIG welded, ensuring long-lasting durability, corrosion resistance, and a precise fit.
