Let your RS sound as purposeful as it looks.
This non-resonated Milltek brings more of the twin-turbo V6 into the drive, with valved rear silencers and substantial oval tips. It is the louder cat-back choice for the GPF-equipped RS4 Avant and RS5 Sportback, retaining the particulate filters ahead of the system.
SKUs: SSXAU829, SSXAU830, SSXAU831, SSXAU832
The large oval tips are a noticeable part of the RS rear end. Polished metal makes them stand out against the diffuser; black gives a more understated finish. Brushed titanium has a muted metallic appearance, while burnt titanium adds a blue-toned accent. These are tailpipe-finish choices; the exhaust body is 304L stainless steel.
