Make the C7’s V8 a bigger part of the drive.
A full exhaust change makes the V8 soundtrack a larger part of enjoying your RS6 or RS7 on track. This Milltek system replaces the exhaust from the downpipes back, including primary and secondary catalyst bypasses, with resonated, non-resonated and Road+ centre-section choices. The original rear trims stay in place, and Stage 2 ECU software is required.
| Configuration | SKU |
|---|---|
| Resonated | SSXAU597 |
| Non-resonated | SSXAU598 |
| Road+ | SSXAU599 |
The change is beneath the car, from the larger downpipes through to the valved rear silencers. Keeping the original trims preserves the familiar rear appearance while giving the V8 a more prominent voice under acceleration. Choose the centre configuration for the sound you want, with the noise limits at your intended venues in mind.
Resonated includes centre silencing for a more restrained note than Non-resonated, which replaces it with pipework. Road+ uses its own centre silencer assembly. All three are full catalyst-bypass systems for track use. If you want 100-cell secondary sports catalysts included, choose the separate full sports-cat package.
Both 76 mm primary-cat-bypass downpipes, left/right secondary connecting bypass pipes, the selected centre section and both ValveSonic rear silencers. The original rear trims and exhaust-valve motors are reused.
Stage 2 ECU software is required, and the lambda-sensor cables need extending. Book the mechanical work and calibration together. The installer transfers the original valve motors and checks sensor routing and clearances around the larger downpipes.

Yes. Stage 2 ECU software is required, and the lambda-sensor cables need extending during fitting.
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.
This package bypasses the primary and secondary catalysts. The separate 100-cell package bypasses the primary catalysts but includes 100-cell secondary sports catalysts. Both are track-use full systems with supporting Stage 2 tuning requirements.
