EGO-X exhaust system for Audi RS5 (FU5) Plug-in Hybrid – Pre-orders now open

ECE certification noise measurement passed - pre-orders have begun

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

The exhaust system has passed the noise measurement required for ECE approval, and pre-orders are now open.

We are currently awaiting only the final approval documents from the German Federal Motor Transport Authority (KBA). As soon as the documents are available, deliveries of the ECE-approved systems can begin.

The entire system has been designed, tested and manufactured as usual in our own factory in Lübeck.

Dual-line 76 mm design – uncompromising flow

The EGO-X exhaust system features a fully dual-line, 76 mm diameter design, consistently engineered for maximum exhaust gas flow.

When the exhaust valves are open, both exhaust gas flows have a continuous 76 mm straight-pipe flow path. Exhaust gases pass directly through the system without being routed through additional silencers.

When the exhaust valves are closed, the exhaust gases are routed through the silencer on each side. This achieves a significantly quieter sound for everyday driving.

The system utilizes the car's original exhaust valve actuators. Control therefore continues via the car's standard logic and existing driving modes.

Operating principle of exhaust valves

Exhaust valves open

• Dual-line 76 mm pipe design
• Continuous straight-pipe exhaust gas path
• Exhaust gases are not routed through silencers
• Maximum flow
• Significantly more powerful, emotional and present soundscape

Exhaust valves closed

• Exhaust gases are routed through two silencers
• Significantly lower noise level
• More pleasant soundscape for everyday driving
• Control remains according to the car's standard logic

Product Features

• Noise measurement required for ECE approval successfully passed
• Currently available for pre-order
• KBA final approval documents are still being processed
• Dual-line design
• 76 mm / 3" throughout the system
• Straight-pipe flow path when exhaust valves are open
• Two silencers when exhaust valves are closed
• Utilization of original exhaust valve actuators
• Control via the car's standard logic
• Installation from the OPF particulate filter onwards
• High-quality stainless steel construction
• Handcrafted silencers
• TIG-welded construction
• Flow-optimized piping
• Highly precise fit
• Designed and manufactured by HG-Motorsport in Lübeck

Designed for the new Audi RS5

The 2.9-litre V6 biturbo engine combined with a plug-in hybrid system places special demands on the design of the exhaust system, space utilization, soundscape and exhaust gas routing.

For this reason, our development team did not simply adapt an existing system for this car model, but designed a completely new exhaust system for the FU5 platform.

The development focused particularly on the following features:

• maximum exhaust gas flow
• lowest possible exhaust gas back pressure
• precisely defined exhaust gas flow paths
• optimal utilization of standard exhaust flap control
• powerful and immersive soundscape when exhaust flaps are open
• pleasant and practical soundscape when exhaust flaps are closed
• high-quality finish and long service life

ECE Approval

The noise measurement required for ECE approval has been successfully passed.

The final approval documents are currently still being processed by the German Federal Motor Transport Authority (KBA). Deliveries of the ECE version will begin as soon as all approval-related documents are finalized.

As the system is currently in the pre-order phase, the final delivery schedule may change depending on the processing time of the competent authority.

Pre-order

By pre-ordering, you secure a system from the first available production batch.

Production and product preparation are already underway. Deliveries will begin as soon as the KBA documentation is complete and the ECE-approved version can be officially delivered.

Scope of Delivery

• EGO-X exhaust system from OPF particulate filter onwards
• Dual-line 76 mm pipe design
• Two integrated silencers
• Mountings for original exhaust valve actuators
• Necessary installation accessories

The car's original exhaust valve actuators are reused and are not included in the scope of delivery.

EGO-X – two soundscapes, one system

When the exhaust valves are open, the system offers an uncompromising, dual-line 76 mm straight-pipe exhaust gas path.

The new EGO-X exhaust system combines maximum flow and an immersive soundscape with the everyday usability provided by standard exhaust flap control.

When the exhaust valves are closed, the exhaust gases from both cylinder banks are routed through a specially designed pipe structure via two silencers located on the driver's side.

This effectively dampens the sound of the exhaust system and produces a pleasantly subdued sound for everyday driving.

ECE certified. Pre-order now and secure one of the first EGO-X systems for the new Audi RS5 FU5.
