Audi A3 S3 Quattro

Audi S3 – Backbox Delete Rear Section Upgrade at MIJ Exhaust! 🔥

This Audi S3 came into MIJ Exhaust for a backbox delete rear section, designed to bring out a more aggressive tone while enhancing the car’s already sporty presence. 😎💨

We removed the factory backbox and fabricated a custom rear section, improving exhaust flow and unlocking a deeper, sharper exhaust note across the rev range.

The setup is finished with a quad exit layout, fitted with carbon fibre tips, giving the rear a premium, high-performance look that perfectly complements the S3’s styling.

The result is a bold transformation — subtle enough for daily driving, but with a much more exciting sound when you put your foot down.

Check out the sound test in the link below to hear how it performs. 🎥🔊
