304 Stainless Steel Valved Cat-Back Exhaust System for Audi S4 B8 & S5 B8 3.0 TFSI
Upgrade your Audi S4 B8 or Audi S5 B8 3.0T with this complete cat-back valved exhaust system, designed to deliver a deeper, louder and more aggressive exhaust note while giving you full control over the sound when required.
Manufactured from high-quality 304 stainless steel, this Audi S4 / S5 performance exhaust offers excellent durability, corrosion resistance and long-term reliability while providing a freer-flowing exhaust path compared with the factory cat-back system.
The integrated electronic exhaust valves allow you to control the exhaust sound using the included remote controller. At the press of a button, the valves can be closed for a quieter and more refined sound or opened for a louder, more aggressive 3.0 TFSI V6 exhaust note.
This Audi S4 B8 / S5 B8 valved exhaust is ideal for drivers who want more sound and character during spirited driving while still having the option to keep the exhaust quieter for normal road use, motorway driving or early-morning starts.
The performance-oriented exhaust layout uses approximately 63mm / 2.5-inch pipework and helps reduce unnecessary restriction through the cat-back section, improving exhaust gas flow and enhancing the distinctive sound of the 3.0 TFSI supercharged V6.
The system is suitable for both standard and tuned vehicles and provides a strong foundation for an upgraded Audi S4 B8 or S5 B8 performance exhaust setup.
The exhaust is designed for plug-and-play installation using the supplied clamps and factory mounting locations, with welding normally not required.
Professional installation is recommended.
