Precision meets aggression, made to thrill, built to last.


Unleash the true potential of your Audi RS3 8Y Sedan with our precision-engineered cat-back exhaust system, designed exclusively for models from 2021 onwards equipped with the factory valve control system. Built without compromise from high-grade 1.4301 (V2A) stainless steel and a full 2mm wall thickness, this setup delivers an incredibly rich and aggressive tone without drone, even at cruising speeds.

This system replaces the stock exhaust with a straight 3.5-inch pipe layout, maximizing flow and creating a raw, motorsport-inspired sound profile. The factory exhaust valves are fully retained, allowing seamless integration with Audi Drive Select. Choose quiet refinement for daily driving or open up the valves for a deep, forceful tone that commands attention.

For enthusiasts seeking full manual control, an optional valve controller is available separately for $400, allowing fixed open-mode operation at the push of a button.

Installation is completely plug-and-play, with no modifications required. To preserve the RS3b s original design language, the exhaust system includes specially designed transition funnels that align perfectly with the factory rear diffuser, eliminating the double pipe look of the stock setup and creating a flush, OEM+ finish.

Key Features:

  • Premium 1.4301 stainless steel construction with 2mm wall thickness
  • Cat-back design, optimized for maximum sound and flow
  • Straight 3.5" piping b no OPF, no compromises
  • Fully integrates with Audi Drive Select valve control
  • Optional manual valve controller available
  • Plug-and-play installation with factory fitment points
  • Tailpipe funnel adapters included for seamless diffuser alignment

Whether you're cruising quietly through the city or tearing down the autobahn, this exhaust transforms your RS3 into a true driver's machine, subtle when needed, savage when desired.
