Overview

This Milltek Sport cat-back exhaust fits the 2013-2016 Audi S4 sedan (B8.5) with the 3.0 liter supercharged V6. The facelifted B8.5 S4 gets rear silencer delete, resonated and valved Milltek systems, with quad GT-100 tips. Each system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Compared with the factory steel parts it is lighter, flows more freely and gives the engine a clearer, stronger voice under load, without the harsh highway drone of a cheap straight pipe. Every Audi S4 B8.5 system is made from T304L stainless steel with mandrel-bent tubing, so the pipe keeps its full size through each bend and resists corrosion for years. It bolts on with the factory hangers and clamps, with no cutting or welding needed. It swaps the factory exhaust from the catalytic converters back, using 60.3 mm (2.37 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the Sound. Rear Silencer Delete (Loudest) is the Milltek system listed for this car. Resonated (Quieter) keeps a resonator for a deeper tone with less drone when cruising. Valved valves that keep the factory quiet and loud modes.

Then pick an Exhaust Tip Finish: Polished (bright polished stainless), Cerakote Black (a black Cerakote ceramic coating), Brushed Titanium (a brushed titanium finish). The finish changes the look only, not the sound.
