Compatible Vehicles:

  • 2017- Audi S4 B9 3.0 TFSI EA839 Limousine Avant
  • 2017- Audi S5 B9 3.0 TFSI EA839 Cabriolet, Coupé, Sportback

Available options:

  • HJS Ultra High-Performance catalytic converters. Made in Germany most reputed high flow converters for their outstanding characteristics, quality and durability. We offer selection between 200cpsi Euro 5 HD matrix or 200cpsi Euro 6 HD matrix. It is hard to achieve Euro 6 emission requirements with only 200 cpsi matrix, what requires big core diameter and big precious metals loading. That causes significant price increase for those catalytic converters. But we still have alternative options. >> Read more about HJS cats.
  • GESI GEN2 400cpsi made in Canada catalytic converter rated 1000hp for 5in core or 1200hp for 6in core. New GEN2 series provides a significant improvement in exhaust flow over stock and offers the latest emissions technology for model year 2017 and newer. EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California) and will address Check Engine light issues with proper engine setup. Read more about G-Sport by GESI cats.
  • Double-layer heatshielding is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
    Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings.
    It’s very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.
