034 Motorsport - Audi B9 RS5 2.9TT Stainless Steel Downpipes - 034-105-4046

The 034 Motorsport 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 primary flow limitation in the factory exhaust system, 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 to allow 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, 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 as well as beta customers.

  • Increased Horsepower & Torque Throughout the Powerband
  • Quicker Turbocharger Spool & Faster Transient Response (150-300 RPM Quicker Spool)

        Save your money!
        Size: For 1998-2001 E46 Sedan 4-Door, Color: Chrome
        Complete waste of money. I bought these specifically for my 2001 BMW 330i sedan and the fitment was terrible. Tabs don’t align, quality is poor and both grilles fall straight off. Definitely would not recommend!

        Not an exact equivalent to the original two piece design
        Size: For 1998-2001 E46 Sedan 4-Door, Color: Chrome
        Not an exact equivalent to the original two piece design. It won't snap in place as a direct replacement and required some glue. Not sure how long that will last.

        Overall, super happy with it. Didn't expect much since a genuine one is 2-3x the price, but it fits decently (could be better) and isnt super flimsy. It isn't perfect, but its the best youre going to get without buying a genuine OEM one.

        It’s just an air filter
        Size: CA12290-Premium
        It’s exactly how it’s pictured. Not sure what else to say it’s an air filter. I guess it’s doing its job
