EGO-X exhaust system for Audi S5 B10 TFSI Mild-Hybrid quattro

ECE noise test passed – pre-orders have started.

The development of the new EGO-X exhaust system for the Audi S5 B10 TFSI Mild-Hybrid quattro has reached a significant milestone: the system has successfully passed the noise measurement required for ECE approval, and the product is now available for pre-order.

Like all EGO-X exhaust systems from HG-Motorsport, this system is also fully designed, tested, and manufactured at the company's factory in Lübeck, Germany.

2 × 63 mm → 89 mm – flow-optimized exhaust system

EGO-X is designed specifically for the new generation Audi S5 B10 model's 3.0-liter TFSI Mild-Hybrid engine, which produces 270 kW / 367 hp. The exhaust system uses a completely redesigned routing, which is optimized for efficient exhaust gas flow.

In the initial section of the system, exhaust gases travel through two 63 mm pipes. After this, the flows merge into a large-diameter 89 mm (3.5-inch) main pipe.

A significant difference from the original exhaust system is that in the EGO-X system, the original pre-silencer is completely omitted. This achieves efficient exhaust flow and minimal backpressure.

At the rear, the exhaust gases flow through 76 mm piping to the exhaust valves, after which the flow splits into four 63 mm tailpipes.

Exhaust construction:

2 × 63 mm → 1 × 89 mm → 76 mm to exhaust valves → 4 × 63 mm tailpipes

Operation of exhaust valves

When valves are open

  • Performance-oriented exhaust path

  • 89 mm (3.5-inch) main pipe

  • 76 mm piping to exhaust valves

  • Flow splits into four 63 mm tailpipes

  • Original pre-silencer removed

  • Efficient exhaust flow

  • Louder, sportier, and more distinct sound profile

When valves are closed

  • Exhaust gas flow is routed through the integrated silencing structure

  • Noise level drops significantly

  • More subtle sound profile for daily driving

Audi S5 B10 TFSI Mild-Hybrid quattro

  • Engine code: DWVA

  • Transmission code: ECRA

  • Displacement: 2,995 cm³

  • Power: 270 kW / 367 hp

  • Fuel: gasoline / electric

  • Production from: 07/2024

Designed for the Audi S5 B10 TFSI Mild-Hybrid quattro

The EGO-X exhaust system has been developed specifically for the Audi S5 B10 TFSI Mild-Hybrid quattro, which features a 2,995 cm³ engine and 270 kW / 367 hp of power.

Rather than adapting a finished exhaust, the structure and routing of the system have been designed to meet the technical requirements of the new S5 B10 generation and the characteristics of the DWVA engine.

Two 63 mm exhaust streams are combined into a large-diameter 89 mm main pipe. The original pre-silencer is omitted, and at the rear, the exhaust flows through 76 mm piping to the exhaust valves. Finally, the flow splits into four 63 mm tailpipes.

Development focused specifically on the following features:

  • Efficient exhaust flow

  • Minimal exhaust backpressure

  • Removal of original pre-silencer structure

  • Efficient combination of two exhaust streams

  • Large 89 mm diameter main pipe

  • 76 mm piping to exhaust valves

  • Four 63 mm tailpipes

  • Powerful and sporty sound when valves are open

  • More pleasant sound level during daily driving when valves are closed

  • High-quality finish and long service life

ECE approval

The noise measurement required for ECE approval has been passed. According to the product description, the system is supplied with the corresponding ECE approval certificate.

The use of the exhaust system in road traffic in accordance with the approval and any potential need to update vehicle registration documents are determined by the final approval documentation and the correspondence between the vehicle and the approved application.

EGO-X – two sound worlds, one exhaust system

The EGO-X exhaust system developed for the Audi S5 B10 optimizes exhaust flow immediately after the OPF particulate filter. The original pre-silencer is completely omitted, and the two 63 mm exhaust streams merge into a large 89 mm main pipe.

After this, the exhaust gases travel through 76 mm piping to the exhaust valves and split into four 63 mm tailpipes.

With the valves open, the system offers a more powerful and sporty sound profile. With the valves closed, the exhaust flow is directed through the integrated silencing structure, which reduces the noise level and improves driving comfort for daily use.

The new EGO-X combines a flow-optimized design, a large 89 mm main pipe, and the removal of the original pre-silencer solution with two different sound profiles.

ECE noise measurement passed. Pre-order now and secure yourself one of the first EGO-X exhaust systems for the new Audi S5 B10 TFSI Mild-Hybrid quattro model.
