High-performance hybrids just got a whole lot more exciting. Milltek exhausts for Porsche and BMW hybrids made their debut at the 2025 Goodwood Festival of Speed, and they’re turning heads, not just with power, but with sound.
Milltek’s latest additions bring new life to hybrid icons: the BMW M5 G90 PHEV and the Porsche 992.2 Carrera Hybrid. These aren’t just any upgrades, they’re purpose-built to unleash thrilling sound without compromising on emissions or quality.
Enhanced Exhaust Sound for BMW M5 G90 PHEV
The new system for the BMW M5 G90 Plug-In Hybrid is more than a style statement. Behind its sleek finish lies a non-resonated, particulate filter-back setup designed to deliver an aggressive tone.
With a combined power output of 727 hp from its 4.4-litre V8 and electric motor, the M5 is no slouch. Now, thanks to Milltek’s engineering, drivers get the acoustic thrill to match. A noticeable difference in volume and character is evident when the valves are open versus closed, and a Milltek controller option lets enthusiasts override factory valve settings.
The system is compatible with UK, USA, and global versions of the M5 G90, including the Touring (G99) model. Customers can choose from polished stainless, cerakote black, brushed titanium, or burnt titanium trims.
Porsche 992.2 Carrera Hybrid Prototype Packs a Punch
Milltek didn’t stop with BMW. Porsche fans will be pleased to hear that a prototype OPF/GPF back exhaust system has been developed for the new 478 hp 3.6-litre Porsche 992.2 GTS Hybrid.
While still in development, production is expected soon. This new system enhances the rich tone of Porsche’s hybrid setup, promising a more involving experience for drivers craving the sound of a classic flat-six.
Designed for Power and Built to Last
Both systems are designed to fit after the existing particulate filters. This clever approach ensures that emissions compliance remains unchanged while performance sound is dramatically improved.
Milltek’s exhausts are crafted using high-grade T304L stainless steel and engineered in Derbyshire by a team of skilled specialists. Quality, durability, and performance are at the core of every product they produce.
Making Hybrids Feel More Engaging
There’s no question that today’s performance hybrids pack serious punch. But Milltek understands that sound plays a huge role in how connected drivers feel to their machines.
As Kev Hall, Technical Operations Manager at Milltek, puts it: “Just because these hybrid models use some form of battery power to boost their performance, it doesn’t mean their drivers should be deprived of the best sound output from their pleasurable petrol engines.”
Summary
With these new exhaust systems, Milltek is helping hybrid super-sedans and sports cars find their voice again. Whether it’s the raw energy of the M5 G90 or the sharp precision of the Porsche 992.2 Hybrid, drivers can now enjoy the full experience, performance, presence, and unmistakable sound.
