Audi A4 S Line 2012

Service Completed: Turbo-Back Exhaust System Upgrade

At MIJ Exhaust Ltd, we recently completed a full turbo-back exhaust upgrade on this Audi A4 S Line (2012) petrol, transforming both its performance and sound to match its sleek styling.

The factory system was replaced with a custom-fabricated turbo-back setup, designed to significantly improve exhaust flow from the turbocharger onwards. This upgrade delivers a sharper throttle response and a much deeper, more purposeful exhaust note throughout the rev range.

To complement the vehicle’s Black Edition styling, the system was finished with matte black exhaust tips, giving it a clean, aggressive look at the rear. The result is a car that now sounds as bold as it looks, with a refined tone during normal driving and a more pronounced growl under acceleration.

As with all of our work, this exhaust was hand-built in-house using premium T304 stainless steel and expertly TIG welded, ensuring long-lasting durability, a precise fit, and a high-quality finish.

Be sure to check out the sound test video to hear how this setup brings the Audi to life.
