Milltek Sport Cat-Back Exhaust - 2017-2024 Alfa Romeo Giulia Quadrifoglio

This Milltek Sport cat-back exhaust fits the 2017-2024 Alfa Romeo Giulia Quadrifoglio with the 2.9 liter twin-turbo V6. This valved Milltek system for the Giulia Quadrifoglio uses an X-pipe and a single rear silencer to give the Ferrari-derived twin-turbo V6 a sharper, more exotic sound while keeping the factory quiet mode. 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. The Giulia Quadrifoglio parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at 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 70 mm (2.76 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Pick an Exhaust Tip Finish: Cerakote Black (a black Cerakote ceramic coating), Polished (bright polished stainless), Carbon Fiber (carbon fiber outer sleeves), Brushed Titanium (a brushed titanium finish), Burnt Titanium (a heat-blued burnt titanium finish). The finish changes the look only, not the sound.

Valve Remote: choose Add Valve Remote to include the Milltek Active Valve Control remote, a plug-and-play module that lets you open and close the exhaust valves yourself. It is only offered on systems that keep valves.

Planning more power? Milltek also makes downpipes for the Giulia Quadrifoglio.
