034Motorsport Stainless Steel Racing Catalyst, B9/B9.5 Audi SQ5
Optimized for increased flow and maximum performance, the Stainless Steel Racing Catalyst features a massive 148mm diameter Euro4 racing catalytic converter in the factory location. This complete drop-in solution includes an integrated v-band flange at the turbine outlet, an 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 SQ5 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 transfer into the engine bay.
034Motorsport's Stainless Steel Racing Catalyst was developed entirely in-house on 034Motorsport's Development B9 Audi SQ5, utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques. Final production units were then tested extensively on track in B9 and B9.5 Audi SQ5 vehicles before release.
