Milltek Sport Cat-Back Exhaust - 2015-2018 BMW M3 F80

This Milltek Sport cat-back exhaust fits the 2015-2018 BMW M3 and M3 Competition sedan (F80) with the 3.0 liter S55 twin-turbo six. The S55 M3 sounds muted from the factory, and a 70 mm Milltek cat-back gives it a harder, cleaner six-cylinder voice, with road, race and equal-length versions. 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 BMW M3 F80 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

Start with the Sound. Equal Length, No Centre Silencer replaces the centre silencer with equal-length pipes for a sharper, smoother-revving S55 sound. Road, Centre and Rear Silencers keeps a centre silencer and a rear silencer for the most refined tone of the three. Race, Race Centre Silencer swaps in a free-flowing race centre silencer ahead of the rear silencer for a louder, more aggressive note.

Then pick an Exhaust Tip Finish: Polished (bright polished stainless), Cerakote Black (a black Cerakote ceramic coating), 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.
