Does this fit my vehicle?

Unleash the full potential of your Audi RS4 B9 or RS5 F5 with the CRT Performance Catless Downpipe, engineered specifically for the EA839 DECD / DECAJ engine platform. Designed for European OPF/GPF-equipped models, this downpipe delivers dramatically improved exhaust flow, reduced backpressure, and a sharper, more aggressive exhaust note.

Key Features

  • Reduced Backpressure – Enhances turbo spool, throttle response, and overall performance.

  • Weight Savings – Significantly lighter than the restrictive OEM catalytic setup.

  • Optimized Flow – Smooth, mandrel-bent tubing eliminates turbulence for efficient exhaust gas velocity.

  • Aggressive Exhaust Tone – Deep, motorsport-inspired sound without unwanted drone.

  • Thermal Protection – Wrapped with a premium high-temperature heat shield for maximum safety and efficiency.

Materials & Construction

  • Handcrafted from 304-Grade Stainless Steel – Corrosion-resistant and built to withstand extreme heat.

  • Precision CNC-Machined Flanges – Ensures perfect OEM fitment and leak-free connection.

  • TIG-Welded for Strength – Professional motorsport-grade craftsmanship.

  • Thermally Insulated Exterior – Reduces engine bay temperatures and protects adjacent components.

Testing & Durability

Every CRT Performance Downpipe is track and road tested under high-stress conditions to guarantee exceptional durability, fitment precision, and consistent performance.

Important Notice

  • This downpipe replaces the factory catalytic converters.

  • Check Engine Light (CEL) may occur depending on the vehicle’s ECU calibration.

  • CRT cannot guarantee emissions compliance – for off-road or motorsport use only.

  • Designed exclusively for EU models equipped with OPF/GPF filters.

Compatibility

  • Audi RS4 B9 (2019–2024, EU)

  • Audi RS5 F5 (2019–2024, EU)

For OPF/GPF-equipped vehicles only.
