EGO-X exhaust system for Audi RS6 / RS7 C8 quattro – with ECE, now available

Development complete. ECE approval available. Order now.

The new EGO-X performance exhaust system for the Audi RS6 / RS7 C8 quattro has been fully developed, successfully tested and is available now.

The system was developed specifically for the powerful 4.0-litre V8 biturbo and combines maximum exhaust throughput, an emotional V8 sound and the usual high-quality workmanship of our EGO-X product line.

The ECE approval is fully available. Delivery can take place immediately.

Like all EGO-X systems, this exhaust system was developed, tested and manufactured in our manufactory in Lübeck.

Developed for maximum flow and uncompromising V8 sound

The EGO-X exhaust system was developed specifically for the Audi RS6 / RS7 C8 and is built entirely dual-channel in 76 mm (3 inch) from the standard Y-pipes back.

The consistent full-flow design reduces exhaust back pressure and creates ideal conditions for high exhaust throughput, both in standard condition and on performance-tuned vehicles.

Two specially tuned absorption rear silencers in conjunction with the two electronic exhaust valves provide the perfect balance between powerful V8 sound and pleasant everyday usability.

With the valves open, a continuous 76 mm exhaust path is available. With the valves closed, the exhaust gases are routed through the specially developed silencer routing and the noise level is significantly reduced.

The result: maximum flow with the valves open and a pleasantly restrained sound in everyday use.

Development at HG-Motorsport

The development of the EGO-X exhaust system for the Audi RS6 / RS7 C8 is fully complete.

During development the system went through extensive testing and optimisation steps:

• 3D design

• Development of the pipe routing

• Flow optimisation

• Sound tuning

• Prototype construction

• Vehicle tests

• Fit check

• Endurance testing

Our aim was not simply to develop a louder exhaust system, but a fully matched overall system of performance, sound and everyday usability.

The generously dimensioned 76 mm piping and the specially developed silencers allow high exhaust throughput without having to give up the benefits of an electronically controlled valved exhaust system.

With ECE approval – legal and no registration entry required

The ECE test has been completed successfully and the required approval documents are available.

The EGO-X exhaust system has an ECE approval and can be used legally on public roads within the approved scope of use without any additional entry in the vehicle documents.

Note: The information on the ECE approval applies to the correspondingly approved product variant. When choosing a variant with the Bull-X Tronic control unit, the respective approval conditions must be observed.

Order now – ECE documents available

Development is complete, the ECE approval is available and the exhaust system can be ordered now.

This ends the previous wait for the approval documents. Delivery can take place.

Secure the new EGO-X exhaust system for your Audi RS6 or RS7 C8 now and experience the difference between the standard V8 sound and an exhaust system developed consistently for performance.

EGO-X – two sound characters, one system

Valves open – maximum full flow

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

The exhaust gases are routed directly through the system without being diverted through the silencers.

This ensures:

• Maximum exhaust throughput

• Low exhaust back pressure

• Powerful, present V8 sound

• Emotional sound with the valves open

Valves closed – pleasant in everyday use

With the valves closed, the exhaust gases from both cylinder banks are routed through the specially developed piping via the two silencers.

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

The EGO-X thus combines two different sound characters in one system: emotional and powerful with the valves open, restrained and comfortable with the valves closed.

EGO-X – performance and quality from our own production

HG-Motorsport has been developing and manufacturing high-quality performance exhaust systems for demanding drivers since 1996.

With the EGO-X exhaust system for the Audi RS6 / RS7 C8 we continue this tradition consistently.

Dual-channel 76 mm, two electronic exhaust valves, hand-made absorption rear silencers and a flow-optimised stainless steel construction.

Maximum flow. Unmistakable V8 sound. Legal with ECE.
