Make the V8 part of the event.
Give the C7 RS6 or RS7 a V8 soundtrack to make a track day feel special. This full Milltek system combines primary-cat bypass downpipes, 100-cell secondary sports catalysts and valved rear silencers. Three centre-section choices let you choose the exhaust character, while the original tailpipe trims keep the familiar RS finish. A Stage 2 ECU remap is required.

| Road+ | SSXAU594 |
| Non-resonated | SSXAU595 |
| Resonated | SSXAU596 |
The appeal goes beyond new tailpipes: this changes the exhaust from the downpipes back, giving the engine a more prominent voice as you accelerate. Keeping the original trims lets you enjoy that change without altering the rear styling. It is a full system for track use, so the noise limits at your chosen venues matter when choosing the sound.
We would start with Resonated if you want the more restrained choice beside Non-resonated, which replaces the centre silencer with pipework for a louder note. Road+ uses a different centre silencer assembly. All three include the same 100-cell secondary sports catalysts and valved rear silencers; the centre section is what changes. Road+ is a sound configuration name, not road approval.
Both downpipes, left and right 100-cell catalyst assemblies, the selected centre section and both ValveSonic rear silencers are included. Your original rear trims and valve motors are reused.
Arrange the installation and Stage 2 calibration together. The lambda-sensor cables need extending, and the original valve motors transfer to the new rear silencers. The installer also needs to align the system without strain and check sensor routing and clearances around the larger downpipes.

No. Road+ names the sound configuration here. This complete package is designated for track use and needs a Stage 2 ECU remap.
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.
Yes. This package uses the original tailpipe trims and valve motors, so you can change the exhaust beneath the car while keeping the familiar RS rear appearance.
