EGO-X Performance for the Audi C7 generation – pre-orders have started.
Pre-order now and secure one of the first exhaust systems from the new production batch.
The new EGO-X Performance exhaust system for Audi S6, RS6, S7 and RS7 C7 models combines a powerful V8 soundscape, high-quality finish, and an exhaust structure designed specifically for the vehicle.
Designed for the 4.0-liter V8 TFSI twin-turbo engine, the EGO-X offers a more immersive sound, efficient exhaust flow, and the renowned quality of HG-Motorsport’s in-house manufacturing.
The exhaust system is now available for pre-order.
The product development, design, and manufacturing take place at the HG-Motorsport factory in Lübeck, Germany.
Designed for efficient flow and powerful V8 sound
The Audi C7 generation 4.0-liter V8 biturbo engine provides an excellent starting point for a performance exhaust system that emphasizes the engine’s characteristic sound and efficient exhaust gas flow.
The new EGO-X has been developed to guide exhaust gases through the entire system as efficiently as possible. In addition, the electronically controlled exhaust flap design allows for two different soundscapes.
The flow-optimized piping and carefully sized mufflers combine a powerful V8 sound with pleasant driving comfort for daily use.
The goal is the most unobstructed exhaust flow possible, low backpressure, and two different sound profiles in one system.
EGO-X – two soundscapes, one exhaust system
Exhaust flaps open – powerful V8 sound
When the flaps are open, exhaust gases are routed along the most direct path possible.
This enables:
-
Efficient exhaust flow
-
The lowest possible exhaust backpressure
-
A powerful and distinctive V8 soundscape
-
A sportier and more immersive sound when the flaps are open
Exhaust flaps closed – comfort for daily driving
When the flaps are closed, the exhaust flow is directed along the path designed for the system's muffler.
This reduces noise levels and produces a more restrained sound for daily driving.
EGO-X combines sporty sound with the practicality offered by a flap-controlled exhaust system.
