Enhance sound, performance, and durability on your Audi RS4 or RS5 2.9T with the STRATEC 304 Stainless Steel Valved Cat-Back Exhaust System. Engineered for drivers who want aggressive sound on demand with everyday refinement, this system delivers a powerful motorsport-inspired exhaust note when valves are open and a quieter, OEM-like tone when closed.
Constructed from high-quality 304 stainless steel, this exhaust offers excellent heat resistance, corrosion protection, and long-term reliability while remaining lighter than the factory exhaust. The valved muffler design provides instant sound control, making it ideal for both daily driving and spirited performance use.
