The RS Q8 can cover distance with very little fuss. This resonated Milltek OPF-back gives its V8 a more noticeable voice while keeping the original tailpipe trims and factory filters on OPF-equipped cars. It is the sound upgrade for an owner who likes the Audi’s appearance and wants more character from behind the wheel.
SKU: SSXAU957
Retaining the original trims means the RS Q8 still looks familiar from the rear; the pleasure of the upgrade is in the exhaust note when you drive it. Front silencers make this the more restrained choice beside the non-resonated SSXAU899. We would start here for an owner who enjoys the V8 but also uses the car for longer journeys with passengers. Active valve control remains part of the system’s changing character.
Front flexi pipes, front silencers, 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. On an OPF-equipped RSQ8 the filters remain in place.
The resonated SSXAU957 includes front silencers. The non-resonated SSXAU899 replaces them with pipes for a louder character.
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.
No. SSXAU957 retains them. It is a good choice if you want to keep the factory rear styling and put the investment into the exhaust beneath it.
