Constructed from premium 304 stainless steel with precision TIG welding, it provides long-term durability, corrosion resistance, and a clean OEM-style finish. Fully bolt-on with no cutting or welding required, installation is straightforward for most professional exhaust shops. Tuned specifically for the updated 3.0T V6 in the facelift B9.5 S4, it delivers a deeper and more dynamic exhaust note compared to the factory setup, especially when the valve is open.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFitment: Compatible with Audi S4 (B9.5 Platform, 2020–2024), sedan and Avant.
