Hear more of your RS6 or RS7.
If a restrained exhaust leaves your C8 RS6 or RS7 feeling quieter than you would like, this non-resonated Milltek system puts more emphasis on the V8 soundtrack. Twin 80 mm pipework, an active centre section and a choice of polished or black oval tips bring sound and appearance together in one upgrade.
| Configuration | SKU |
|---|---|
| Polished Oval | SSXAU903 |
| Cerakote Black Oval | SSXAU904 |
Removing the front silencers from the Milltek configuration makes this the more vocal choice alongside the resonated equivalent. That suits an owner who actively wants to hear the V8 more often, rather than only noticing new tailpipes when the car is parked. Think about your regular cruise as well as acceleration: non-resonated is a sound preference, and cabin resonance can vary with the car, load and the rest of the exhaust.
Choose polished oval tips for a bright finish or Cerakote black for a darker rear view. Both choices have the same non-resonated layout. For a daily car where a quieter cruise comes first, we would look at the compatible resonated alternative.
The package includes front silencer replacement pipes, active centre, connecting pipes, rear sections, valved outlets, the selected oval trims and associated fitting hardware. SSXAU903/904 use left and right connecting pipes to the OE downpipe flanges.
Professional installation is recommended. The front connections, chassis-brace spacers, active-valve wiring and tailpipes need to be fitted and aligned together. Match the selected system to the original downpipes and the car's OPF configuration before fitting.

This is Non-resonated. It replaces the front silencers with pipes for a louder result; choose a compatible resonated system if a quieter balance matters more.
Yes. The specified oval trims are part of the complete system. Their finish changes the look rather than the exhaust’s resonated or non-resonated construction.
No. This is the cat-back package. Downpipes and any separate catalyst changes are outside this purchase.
The finish changes the appearance of the tips. It does not change the underlying exhaust configuration shown in the option table.
Let the exhaust cool before cleaning. Wash road salt and dirt from the tips regularly with a soft cloth and a non-abrasive cleaner suitable for their finish. Have any new rattle checked for loose fittings or contact with the bodywork.
Choose this if a more prominent V8 note is a priority. If you want a more restrained sound on regular longer journeys, we would start with the compatible resonated system. The connection and OPF specification must also match the car; those are separate from the sound choice.
Model year, engine, drivetrain, hardware and existing modifications can all change what fits. Check the applications and supplier notes above, or send us your exact vehicle and setup before ordering.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
