The S8 (D4) 4.0 TFSI Quattro Tiptronic is a very special car which manages to blend seriously impressive sportiness with extreme comfort. Milltek set out to develop an exhaust that builds on those qualities without disrupting that finely judged balancing act.
All Milltek exhausts for the 2013+ S8 4.0 TFSI include the same electronic valves as the OE
system that came from the factory. The electronic valve system will function the same in the Milltek catbacks.
Milltek Sport's engineers knew from their extensive work on the S6/S7, that extracting a truly spine-tingling sound from the S8's V8 engine was always possible, but the impressive part is how they've managed to ensure it doesn't become intrusive in the cabin.
The system is based around 2.76mm (70mm) stainless steel pipework. Milltek Sport uses only the finest aircraft-grade stainless steel in the construction of all of its systems, which carry a lifetime guarantee for the original owner.
