Replacement Rear Conversion

A Complete Quad-Outlet Upgrade for the Audi A5 / S5 B9.5

Replace the factory lower rear valance with a model-specific diffuser and matching left-and-right exhaust outlet kit. Choose from four designs ranging from an OEM+ S5-style profile to a more aggressive motorsport look.

Replacement DesignNot a tape-on cover

Quad-Outlet LayoutBalanced left and right profile

Four Style OptionsFrom clean to aggressive

Photo ConfirmationRear configuration checked

More Than a Cosmetic Add-On

This kit changes the complete lower rear presentation rather than placing small fins or trim over the factory diffuser. The original lower diffuser or valance is removed, allowing the new diffuser and quad-style outlet assemblies to form one coordinated rear-end conversion.

Important: fitment must be confirmed by vehicle photo. Do not order by model year alone. Rear bumper type, body style and factory exhaust layout can change the required configuration.

Choose Your Diffuser Style

S5 Style

The cleanest OEM+ option, with defined center fins and a balanced quad-outlet appearance.

ABT-Inspired Style

A more sculpted lower profile with stronger edge definition and a tuner-focused look.

LED Center-Light Style

Adds a central light detail for a modern motorsport theme. Electrical connection is required.

Aggressive Motorsport Style

The most angular design, using deeper fins and sharper contours for maximum visual impact.

Diffuser shape, outlet finish, center light and connecting components vary by selected style. Review the corresponding option images before ordering.

Frequently Asked Questions

Is this an adhesive diffuser overlay?

No. It is a replacement-style conversion. The factory lower diffuser or valance must be removed before installation.

Does it fit every 2020–2024 Audi A5 or S5?

No. Fitment depends on the rear bumper, body style and exhaust layout. Vehicle photos are required for confirmation.

Does it fit both S line and non-S line bumpers?

These bumpers can use different shapes and mounting points. Availability and the correct configuration must be confirmed from a rear-view photo.

Does the factory exhaust need to be modified?

Cutting or pipe adjustment may be necessary depending on the original exhaust direction and outlet position. Test-fit all components first.

Does the LED style require wiring?

Yes. The center light requires electrical connection and testing by a qualified installer.

Is a complete exhaust system included?

No. This is a diffuser and exhaust outlet conversion kit, not a complete cat-back exhaust, muffler system or engine-performance upgrade.
