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)

        Just so so okay... not too stylish but is functional, priced a bit high for basic backpack
        Color: Black, Size: 15.6 Inch
        This is simply a basic backpack that is comparable to below $30 laptop backpacks out there, the only thing really that is stylish design in regard to color is the inside fabric color. I've gotten my wife other laptop bags that actually have more style on the outside and yet cost less. Very very basic packpack, just a tad bit overpriced. It actually looks like a middle school backpack if you think about it's plain design and those you can find under $25, the laptop compartment is just 20% better than than school backpacks.

        Durable Material & Lots of Pockets
        Color: Black, Size: 15.6 Inch
        This backpack is perfect for going to work or going on a trip. The several compartments within each section of the backpack make it super easy to keep things organized and separated. What I like: * Pockets & Compartments - With 3 main compartments, each with additional pockets and zippered sections within, a front pocket, and two water bottle pockets on the sides, this backpack is definitely not lacking when it comes to organization and space. It is extremely spacious and has more pockets inside each section than I would have imagined. There's a place for everything - big and small! * Material - The water-resistant material has a nice matte finish and resists water. It is durable and feels like it will hold up well with regular use. The zipper pulls are some of the best quality I've seen for a bag at this price point. They don't feel cheap or like they're going to come off after regular use. * Comfort & Convenience - The shoulder straps have a decent amount of padding without being bulky, making the backpack feel more elevated than a typical school backpack. I LOVE the strap across the back of the bag. It makes traveling and moving through the airport a breeze - just slide the strap over your suitcase handle and you don't have to carry the backpack on your back. What could use improvement: * Interior Color - The only complaint I have about this backpack is that the listing says the interior color is tan and the color in the image is a light tan ... but the actual color is a gold color, which is not my style or taste. Despite the discrepancy in the interior color, this backpack is a great option for a variety of uses, and the quality and durability make it a great option for everyday use as well as when you're traveling.

        Stylish and Roomy Multifunctional Laptop Backpack
        Color: Atrovirens, Size: 15.6 Inch
        The GOLF SUPAGS Laptop Backpack is what happens when practicality finally meets clean, understated style. The “Atrovirens” shade is a deep, foresty green color that feels sophisticated and gender-neutral, making it equally perfect for men and women. This is a very good looking, on trend tonal backpack that can last you forever, long after you've graduated. It’s water-resistant (which I immediately tested during a light rain, passed beautifully) and made of a smooth, dense fabric that doesn’t wrinkle or pill. The zippers glide cleanly so no snagging or loose threads. And, most importantly, every pocket has purpose. You get multiple compartments, including a padded section that fits a 15.6” laptop snugly, a front organizer for chargers and pens and a hidden back pocket for valuables (passport, cash, etc. when you're traveling.). What surprised me most though is how comfortable it feels when loaded. The padded straps and breathable back panel distribute weight evenly, which makes long commutes or travel days much easier. It even stands upright on its own, so no more floppy bag collapse under desks. This bag is so efficiently designed to be functional in any instance. In a world full of generic backpacks, this bag looks great and is smart, stylish and built to last. I definitely give GOLF SUPAGS five stars because this bag quietly outperforms the loud, overhyped brands.
