Milltek Sport's Cat-back sports exhaust system dedicated to the Audi S6/S7 C7 4.0 TFSI. The entire system is made of stainless steel and finished with 4 tips. The exhaust is available in a louder Non-resonated version and a quieter Resonated version. The system is compatible with the stock downpipe. The version is equipped with ValveSonic valves.
For MY2016 and newer models, the location of the valves has been changed with the stock rear silencer. For this reason, an extension of the control wires for the valve operation is required.
