Audi A5 SE Quattro (2019) – Rear Section Upgrade (Back Box Delete, Dual Exit) at MIJ Exhaust

This 2019 Audi A5 SE Quattro came into MIJ Exhaust for a custom rear section upgrade, featuring a back box delete and a fabricated dual exit stainless steel system. The goal was to sharpen the sound and enhance the rear-end styling while keeping the refinement expected from a Quattro platform.

Removing the restrictive rear silencer opens up the exhaust note, giving the A5 a deeper, more responsive tone that still remains controlled in everyday driving. The dual rear exit transforms the look completely, adding a sportier, more aggressive presence that suits the A5’s sleek design.

We’ve included before and after images to show the full transformation from factory to custom setup.

The result?
More open, responsive exhaust tone
Back box delete for improved sound character
Dual rear exit for a sportier visual finish
Custom stainless steel fabrication with OEM+ fitment
