Enjoy a richer exhaust note from your RS5 Sportback.
A good exhaust makes the RS5 Sportback's V6 something you look forward to hearing. This Milltek cat-back gives the 2018-2019 non-GPF B9 Sportback a choice of Resonated or Road+ construction and four oval finishes. Both use valved rear silencers, with the choice centred on how much silencing you want through the rest of the system.
We would choose Resonated for a car that spends plenty of time cruising: it includes front and centre silencers as well as the valved rear silencers. Road+ keeps the same rear silencer type but leaves out the front and centre silencers. Choose the layout first, then use the finish to give the back of the car your preferred look.
Each row is one complete system. Select the matching option and part number when ordering.

Audi RS5 B9 2.9 V6 Turbo Sportback, 2018-2019, non-OPF/GPF models
For the pre-facelift B9 Sportback without GPFs. It is not the B9 Coupe system or the B9.5 Sportback kit. Allow approximately 2-2.5 hours for fitting, including removal of the original exhaust. A professional installation gives the pipework, tip alignment and hot clearances the attention they need. The system should be checked again after its first heat cycle.
Clean the tailpipes regularly once they are cool, so road dirt and deposits do not become a bigger job later. Use a cleaning product suitable for your chosen tailpipe finish.

Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
We would choose Resonated for frequent cruising. It has front and centre silencers as well as the valved rear silencers. Road+ retains the same rear-silencer type but omits the front and centre silencers.
No. This is the non-OPF/GPF application. A car with factory particulate filters needs the matching GPF-equipped system.
No remap is required for this cat-back change with the rest of the exhaust in its standard configuration. Different requirements can apply if you also change downpipes or catalysts.
The silencer and pipe configuration determine the sound. Pick the finish for the look you want: changing the decorative tips within the same system layout is an appearance choice.
