Double the M3, double the noise. For this shoot we lined up two BMW G80 M3 sedans, one black and one yellow, that both came to our workshop in Woerden for exactly the same upgrade: a DCE Parts high flow single midpipe combined with OPF delete coding. Same car, same parts, two very different colours, and a perfect way to show what this setup does.
The S58 twin-turbo straight-six is a brilliant engine, but in standard form the G80 M3 exhaust is heavily muffled. In standard form, the factory midpipe carries resonators and bends designed mainly to keep the sound down. The DCE Parts S58 high flow single midpipe swaps that section for one straight, large-diameter pipe. Less restriction and less weight, and above all a far more present sound: deeper at idle, harder and rawer under full load, with more crackle on the overrun. Because the midpipe connects to the factory rear silencer, the valves still work as standard, so you can keep things civil by selecting a quieter exhaust mode when you need to.
The second part of this build is software. Both cars received OPF/GPF delete coding, which adapts the engine control so the S58 runs without the factory particulate filters and without fault codes. Removing the OPF frees up the exhaust flow even further and makes the single midpipe sound even more pronounced. Please note that OPF delete coding is intended for off-road and motorsport use only and should only be used where local law allows it. Our team will gladly explain the options and what is legal in your situation before any work starts.
For owners comparing G80 M3 midpipe options, the single midpipe is the choice for the most aggressive sound. It is a bolt-on part that fits the G80 M3 and the G82 M4, and it can be fitted in a few hours with the car on a lift. We check the exhaust hangers and alignment of the tips after installation so everything sits straight and rattle-free.
Want this sound on your own G80 M3 or G82 M4? Order the DCE Parts S58 high flow single midpipe at PSR Parts, or book the full package, midpipe and coding included, in the PSR Parts workshop in Woerden. Both of these M3s were fitted by our own team, and yours can be next.
