Milltek Full System Exhaust for Audi RS6 C7 4.0 TFSI biturbo quattro inc Performance Edition (2013-2018) – Sharper Sound, Reduced Back Pressure
This is Milltek's front-pipe-back system for the Audi RS6 C7 4.0 TFSI biturbo quattro inc Performance Edition. It replaces everything from close to the turbo rearward in one system, combining downpipe, mid-pipe and cat-back into a single upgrade for the biggest gain in flow and the fullest change in exhaust note available on this platform. It's offered in non-resonated, resonated or road+ part resonated versions, so you can pick the setup that suits how the car's used.
It's the option for anyone who wants the complete Milltek transformation in a single fit, rather than building the system up piece by piece.

What's the difference between the resonated and non-resonated versions?
The resonated version adds extra silencing for a quieter, more refined tone. The non-resonated version leaves it out, so it is louder and more aggressive.

Yes. Milltek lists this part for the Audi RS7 C7 Sportback 4.0 V8 TFSI biturbo inc Performance Edition as well as the other models in the fitment list above.
Is it road legal?
Milltek lists this as a race part without EC approval, so it is intended for off-road and competition use.
Do I need a remap?
Some versions do. Milltek notes: "Non Res with 76mm Downpipes and 100cell cats. Uses OE Tips. Requires a stage 2 ECU remap (lambda cables need extending)". Check the notes for the version you choose.
Does it keep the factory catalytic converter?
Yes. It fits behind the factory catalytic converter, which stays in place.

T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
