The 034Motorsport Stainless Steel Racing Catalyst Set for B9 Audi RS5 is designed as a drop-in replacement for the restrictive factory catalytic converters. The Stainless Steel Racing Catalyst Set offers increased horsepower and torque throughout the powerband, reduced turbocharger lag, improved throttle response, and enhanced exhaust note. This upgrade eliminates the factory exhaust system's primary flow limitation, allowing you to maximize the potential of your turbocharged engine.

Optimized for increased flow and maximum performance, the Stainless Steel Racing Catalyst Set features two massive Euro 3 racing catalytic converters in the factory locations. This complete drop-in solution includes an integrated v-band flange at the turbine outlets, integrated oxygen sensor bung after the catalysts, integrated 3-bolt downpipe flanges, and a complete gasket/hardware kit for precise fitment and ease of installation. The Stainless Steel Racing Catalyst for B9 Audi RS5 vehicles is constructed from 304 stainless steel for maximum durability and corrosion resistance. It is TIG-welded and back purged and includes an integrated OE style heat isolation barrier to minimize exhaust heat transferred into the engine bay.

034Motorsport's Stainless Steel Racing Catalyst was developed entirely in-house by 034Motorsport’s Engineering department and tested extensively internally and with beta customers.
