Take your Audi A6 Quattro to the next level with the M.Flow Touring Series Cat-Back Performance Exhaust System, built for 2000–2004 2.7L models. Designed for both long highway drives and weekend adventures, this premium exhaust system delivers dyno-proven performance and a deep, resonant tone that enhances every mile.
 
Engineered from high-quality, corrosion-resistant stainless steel, this system features 2.5” mandrel-bent piping for efficient exhaust flow. The exhaust gases pass through four straight-through mufflers, producing a moderate exterior sound and mild interior tone—ideal for drivers who want added performance and character without overwhelming cabin noise.
 
Finishing off the system is a dual split rear exit with 4” polished, double-wall, angle-cut rolled-edge tips, offering a clean, aggressive appearance that perfectly matches the refined performance of your Audi.
 
The cat-back design replaces all components from the catalytic converter to the rear, giving your A6 Quattro a full performance upgrade. With precision CNC robotic manufacturing and advanced 3D scanning technology, the 16493 system offers a direct-fit, easy bolt-on installation—no cutting or welding required.
