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

        Works great BUT if you make this purchase go ahead and order handle extension because if you don't it will screw your low back up big time. Like I said works great cut great but I haven't tested the run time yet.

        Edged entire corner lot with a sidewalk on one charge of the batteries.
        Style: 2 x 2.0Ah
        Excellent. A bit heavier than my echo gas weed trimmer for reference. Fair balance but it is a bit of a workout. The good thing is I can edge a 10k sq ft corner lot in about 1/3 the time. On the corner, I have both sides of the sidewalk plus the curb side to do. I've owned gas edgers before also. This comes in comparable to the price I paid for one of those 20 years ago so I would also say a good if not very good value for the buck. It was not an initial edging but 1st maintenance for the year and rather overgrown. Didn't even use one full charge on the edger.

        Amazing!!! Works great
        Size: 9 inches
        Works really well. Cit through my Saint Augustine grass like a breeze and it is super thick. Very happy with purchase. Battery has good life, charged it for a full 24hrs before use and it last a long time. They send 2 blades and the battery with charger which is a huge plus because everything else I looked at you had to purchase those separately and it was just as much as the edger. This is a great deal and worth the money. Highly recommend 👌

        Great thing to have.
        Size: 9 inches
        Great thing to have. For my small yard, it is perfect for me. Yes, the battery life does not last as long as I would like be, but I would buy this again. Great power and speed.

        Edging made easy
        Size: 9 inches
        Surprised how well this works. I was looking for no cord for long driveway. The battery takes a bit to fully charge, but lasts for the entire job. The levels for depth make edging around d flower beds or raised beds easy- not really a trench, but gives a good edge. Lightweight and easy to manage. Definitely lighter than my corded edger. The blade is sensitive and the guide to keep it steady along concrete is not great- just need to make sure you watch closely or it will spark when it hits the concrete.
