Audi A1 TDI S Line – Cat-Back Exhaust Upgrade (Mid & Rear, Single Exit to Twin Tip) at MIJ Exhaust

This Audi A1 TDI S Line came into MIJ Exhaust for a custom cat-back exhaust upgrade, featuring a full mid and rear stainless steel system with a single exit conversion to a twin tip finish. The aim was to improve flow, refine the diesel tone, and add a more aggressive S Line-inspired look.

The new cat-back system replaces the restrictive factory setup, allowing the 1.6 TDI to breathe more freely and delivering a cleaner, more responsive exhaust note. The twin tip rear finish completely transforms the look, giving the rear end a sharper, more performance-focused appearance while keeping it subtle and OEM+.

The result?
Improved flow through full cat-back system
Sharper, more refined diesel exhaust tone
Single exit upgraded to twin twin-tip finish
Clean stainless steel fabrication with perfect S Line fitment
