Milltek SSXAU447 Cat-back Quad Tip Valved Street Exhaust Audi C7 S6 and S7
More than 34 years of continuous exhaust development and technical expertise are drawn upon to develop the ultimate Milltek Sport range of performance products. The Milltek SSXAU447 Exhaust is a fully polished T-304 stainless steel, CNC mandrel bent, catback system. The Milltek exhaust begins after the factory catalytic converters and continues back through resonated midpipes to the center muffler and finally to the valved rear mufflers and quad cerakote black 100mm round tips. The Milltek exhaust improves power and response and gives a deeper, more agressive sound. The valves on the rear muffler are controlled by the ECU to open or close as needed depending on vehicle operation.
FITMENT GUIDE: The Milltek SSXAU447 catback exhaust fits the following vehicles:
*Some 2016 and later models have an updated valve location on one rear silencer meaning the wiring loom needs extending to accommodate.
Milltek Exhaust Manufacturing: Milltek exhausts are fully fabricated in the UK from T-304 stainless steel to prevent corrosion and ensure a long life. CNC mandrel bends are used to maximize flow and performance. TIG welding and CNC'ed hangers ensure a perfect fit. Finally the exhausts are fully polished for show car looks.
Milltek Exhaust Install: Installation of Milltek downpipe-back exhausts typically takes 3-4 hours. Basic hand tools are necessary for installation, no cutting or welding is required.
