Audi A7 4G active sound exhaust system sound generator retrofit package

Significantly upgrade your AUDI A7 4G with the original electronic AUDI A7 4G Bi-Turbo exhaust system (known from the powerful Bi-Turbo 3.0TDI / competition models).

We supply you with the complete package for retrofitting the original electronic Bi-Turbo engine sound system in your AUDI A7 4G with V6 3.0TDI diesel engine.

Install the 3.0TDI Bi-Turbo original system (as installed at the factory) instead of the non-adjustable and too quiet solution which is often regularly offered as an "accessory".

Here we create the additional menu item "Engine sound" in your drive select with which you can control the volume completely freely in your MMI (comfort / auto / dynamic).

Finally, you get the noticeably louder and more aggressive sound of the original exhaust system (very similar to a V8 petrol engine) - just like an AUDI A7 Bi-Turbo TDI with this electronic exhaust system "ex works".

Scope of delivery:

• 1x original AUDI A7 4G Bi-TDI rear silencer left with actuator for external noise generation (depending on model)
• 1x original AUDI A7 4G Bi-TDI rear silencer right with actuator for external noise generation (depending on model)
• 2x Original AUDI A7 4G mounting material / pipe clamps
• 1x pre-assembled cable set
• 2x reducing sleeves for converting the "small" pipe guide to pipe guide Bi-Turbo TDI (depending on model)
• 1x ASU MotorSoundPlus additional electronics
• 1x Installation instructions (German)

Installation time: approx. 3 hours

Product attributes:

Retrofitting the original electronic / active exhaust system is generally possible on all AUDI A7 4G models of all years of manufacture (pre-facelift / facelift) as well as all equipment variants with 3.0TDI V6 diesel engine of any power variant.

This retrofitting is possible for all models of all equipment variants and all years of manufacture (pre-facelift / facelift).

No structural changes (e.g. new bumper / new diffuser / welding / bending etc.) are necessary.

The appearance of the rear silencers remains 1:1 identical - AUDI uses the same look here.

The exhaust volume can be controlled via the factory-installed drive select system - the new menu item "Sound tuning" or, in later model years, "Engine sound" will appear there.

This means you can switch between comfort / auto / dynamic from quiet to loud at any time.

You do NOT have THIS option with the regular AUDI retrofit solution (this is generally quieter because it does not have the factory sound and is controlled via the engine/gearbox, so if the exhaust is LOUD the gearbox is also permanently in "S", which can often be annoying.

AUDI regulates the retrofit system more quietly than a factory bi-turbo (a "normal" 3.0TDI should not sound like a "big" bi-turbo).

This original system must be combined with the MotorSoundPlus BLE additional electronics supplied here.

Only by installing this additional electronics, which tells the vehicle that it is installed in a "real" bi-turbo, you get an exhaust sound.

This means that all drive select levels can be continuously adjusted via drive select and the smartphone app.

Complete version of this original system in stainless steel.

Installation and details:

By using the customer service separation point in the exhaust system, with which individual elements of the exhaust system can be separated and reinstalled without much effort, the installation of the engine sound system is particularly easy.

The supplied cable set leads from the new rear silencers via the grommets that are always present at the factory into the interior and is finally connected to the electrical connections in the trunk (rear right).

Tailpipes:

Pre-facelift = round tailpipes

Facelift = square tailpipe (depending on vehicle equipment)

If you want to convert your pre-facelift AUDI to the facelift rear, order the facelift exhaust system. This fits with the new facelift rear bumper.

Important information:

AUDI only offers the original rear silencers supplied here in the corresponding vehicles.

However, the volume of the vehicle changes depending on the drive select setting, which is why there are no registration options.

For this reason, we offer this retrofit package exclusively for SHOW/trade fair vehicles.
