The Stainless Steel Racing Catalyst offers increased horsepower and torque throughout the powerband, reduced turbocharger lag, improved throttle response, and an enhanced exhaust note. This upgrade eliminates the primary flow limitation in the factory exhaust system, allowing you to maximize the potential of your turbocharged engine.\u003c\/p\u003e\n\u003cp\u003eOptimized for increased flow and maximum performance, the Stainless Steel Racing Catalyst features a massive 148mm diameter Euro 4 racing catalytic converter in the factory location. This complete drop-in solution includes an integrated v-band flange at the turbine outlet, integrated oxygen sensor bung after the catalyst, integrated 3-bolt downpipe flanges, and a complete gasket\/hardware kit to allow for precise fitment and ease of installation. The Stainless Steel Racing Catalyst for B9\/B9.5 Audi S4\/S5 vehicles is constructed from 304 stainless steel for maximum durability and corrosion resistance, is TIG-welded, and includes an integrated OE style heat isolation barrier to minimize exhaust heat transferred into the engine bay.\u003c\/p\u003e\n\u003cp\u003e034Motorsport's Stainless Steel Racing Catalyst was developed entirely in-house on 034Motorsport's Development B9 Audi S4 utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques.
