EGO-X exhaust system Audi RS5 B10 TFSI quattro plug-in hybrid 470 kW / 639 hp / with ECE (pre-order)

EGO-X exhaust system for Audi RS5 (FU5) Plug-in Hybrid – now available to pre-order

ECE test passed. Pre-orders have started.

Introductory price for the first production batch

The development of our new EGO-X exhaust system for the Audi RS5 (FU5) Plug-in Hybrid has reached the next decisive milestone:

The system has successfully passed the ECE noise measurement and can be pre-ordered from now on.

As usual, the complete system is developed, tested and manufactured in our manufactory in Lübeck.

Dual-channel 76 mm – uncompromising full flow

The dual-channel 76 mm design was developed consistently for maximum exhaust throughput and low back pressure and tested on the MAHA MSR 500.

With the exhaust valves open, a continuous 76 mm straight-pipe routing is available on both exhaust branches. The exhaust gases are routed directly through the system without being diverted through additional silencers.

With the valves closed, the exhaust gases on both sides are each routed through one silencer. This creates a considerably more restrained sound for everyday driving.

The direct comparison with the standard exhaust system shows the advantage across the rev range:

• up to +35 Nm &  +20 hp across the entire rev range
• Peak: +8.9 hp and +24.1 Nm

The result: lower exhaust back pressure, better throttle response and measurably more performance.

The peak values of 656.1 hp / 818.4 Nm with EGO-X compared with 647.2 hp / 794.3 Nm for the standard system are confirmed by dyno measurements. (see chart)

The system uses the vehicle’s original exhaust valve actuator motors. Control therefore continues to take place via the standard vehicle logic and the existing driving modes. 

Valve logic at a glance

Valves open

• Dual-channel 76 mm piping
• Continuous straight-pipe exhaust path
• No diversion through the silencers
• Maximum flow
• A considerably more emotional and more present sound

Valves closed

• Exhaust gases are routed through two silencers
• Significantly reduced noise level
• A more pleasant sound in everyday use
• Control continues via the standard vehicle logic

Developed for the new Audi RS5

The EGO-X was developed specifically for the new Audi RS5 and its 2.9-litre V6 biturbo plug-in hybrid.

Numerous test runs on the MAHA MSR 500 as well as power and exhaust back pressure measurements were used to tune the pipe cross-section, exhaust routing and the dual-channel 76 mm design optimally to the RS5.
Our development team did not simply adapt an existing system, but developed a completely new system for the FU5 platform.

• • maximum exhaust throughput
  • low exhaust back pressure
  • clearly defined exhaust paths
  • optimal use of the standard valve control
  • powerful sound with the valves open
  • pleasant everyday usability with the valves closed
  • high-quality workmanship and lasting durability
  • up to +35 Nm and +20 hp across the rev range compared with the standard exhaust system – with reduced exhaust back pressure and improved throttle response at the same time.

ECE approval

The noise measurement required for ECE homologation was passed successfully, and an ECE approval is supplied.

The system can therefore be installed legally in Germany without an entry in the vehicle documents.

Note on the introductory price

With your pre-order you secure a system from the first available production series.

Production and preparation are already under way. Shipping will take place as soon as we have manufactured the first batch and the ECE version can be officially delivered.

Scope of delivery

• EGO-X exhaust system from the OPF back
• Dual-channel 76 mm piping
• Two integrated silencers
• Mounts for the original exhaust valve actuator motors
• Required fitting material

The vehicle’s original valve actuator motors are reused and are not part of the scope of delivery.

EGO-X – two sound characters, one system

With the valves open, the system offers an uncompromising dual-channel 76 mm straight exhaust path.

In this way, the new EGO-X exhaust system combines maximum flow and an emotional sound with the everyday usability of the standard valve control.

With the valves closed, the exhaust gases from both cylinder banks are routed through the specially developed piping via the two silencers located on the driver’s side.

In this way the complete exhaust system is damped effectively and a pleasantly restrained sound is achieved for everyday driving.

ECE test passed. Pre-order now and secure one of the first systems for the new Audi RS5 FU5.
