034 Motorsport Australia - Audi B9 A4/A5 2.0 TFSI Stainless Steel Downpipe with Racing Catalyst - 034-105-4043.

034 Motorsport is proud to introduce the all-new Cast Stainless Steel Downpipe with Racing Catalyst for B9 Audi A4/A5 & Allroad models equipped with the longitudinal 2.0 TFSI engine! Designed as a drop-in replacement for the restrictive factory catalytic converter, the Cast Stainless Steel Racing Catalyst offers increased horsepower and torque throughout the powerband, reduced turbocharger lag, improved throttle response, and an 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 Cast Stainless Steel Racing Catalyst features organic geometry and a massive 135mm diameter Euro 3 racing catalytic converter in the factory location. This complete drop-in solution includes an integrated 4-bolt flange at the turbine outlet, integrated oxygen sensor bung after the catalyst, integrated 3-bolt downpipe flange, and a complete gasket/hardware kit to allow for precise fitment and ease of installation. The Cast Stainless Steel Racing Catalyst for B9 Audi A4/A5 & Allroad is constructed from 304 stainless steel and TIG-welded for maximum durability and corrosion resistance.

034Motorsport's Cast Stainless Steel Racing Catalyst was developed entirely in-house on 034Motorsport's Development B9 Audi A4 utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques. Final production units were then tested extensively on multiple enthusiast-owned B9 Audi A4/A5, and Allroad vehicles before release.

  • Increased Horsepower & Torque Throughout the Powerband (+ 22 HP / + 22 TQ Peak)
  • Quicker Turbocharger Spool & Faster Transient Response (100-200 RPM Quicker Spool)

    Service & Maintenance Guide

    Minor Service - Oil Service

    Every 10k is a minor service - oil and filter. Do not follow the factory 15K and go 7k for tuned vehicles. Oil is cheap, engines are not!

    Intermediate Service

    Every 30k is an intermediate service - oil and filter, cabin filter & air filter, brake fluid flush, remote batteries.

    Major Service

    Every 60k is a major service - oil and filter, cabin filter & air filter, remote batteries, brake fluid flush, fuel filter, DSG gearbox oil and filter (unless automatic, manual, tiptronic or multitronic), spark plugs and haldex oil.

    Additional: Water pump & timing belt and poly belt on belt driven engines should be done every 60k.

    Intermediate Service

    Every 90k is another intermediate service - same as 30k plus a poly belt / accessory belt.

    Minor Service - Oil Service

    Every 10k is a minor service - oil and filter. Do not follow the factory 15K and go 7k for tuned vehicles. Oil is cheap, engines are not!

    Every 60k is a major service - oil and filter, cabin filter & air filter, remote batteries, brake fluid flush, fuel filter, DSG gearbox oil and filter (unless automatic, manual, tiptronic or multitronic), spark plugs and haldex oil.

    Additional: Water pump & timing belt and poly belt on belt driven engines should be done every 60k.

    Intermediate Service

    Every 90k is another intermediate service - same as 30k plus a poly belt / accessory belt.

    Replace Haldex fluid every 30k rather than 60k, Gearbox oil change at 40k for DSG is advised. Front and rear differential oils are "longlife" but replace every 60k to be safe.
