Give the RS Q8 a more vocal side.
Choose this non-resonated Milltek system when you want the RS Q8’s V8 soundtrack to be a bigger part of driving it. It replaces the front silencers with pipework and combines an active centre section with valved rear outlets, while the original tailpipe trims keep the familiar Audi finish.
SKU: SSXAU899
This is the option for someone who gets out of the factory car wishing they could hear more of its engine. The non-resonated layout gives sound greater priority than the resonated alternative, so the exhaust becomes a more obvious part of the experience. For a car used mainly on long motorway journeys, we would start with the more restrained resonated SSXAU957.
Front flexi pipes, front silencer replacement pipes, active centre, connecting pipes, rear silencer, valved outlets and fitting hardware. Your original trims are reused.
The front flexi pipes connect to the OE downpipe flanges, avoiding a cut-and-sleeve front joint. Milltek estimates 3-4 hours for fitting. Proper alignment and a check of the active centre and outlet valves complete the installation.

No. The system is designed to use your original RSQ8 trims.
No. On an OPF-equipped RSQ8 the filters remain in place.
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.
SSXAU899 uses front silencer replacement pipes. SSXAU957 has resonated front sections and is the more restrained sound choice. Both keep the original tailpipe trims; choosing non-resonated does not require a different rear appearance.
