Known for its luxury and brute force, the BMW M8 Competition is a grand tourer with serious track potential. With its sleek styling, long-reaching motorsport heritage, and a twin-turbocharged V8 engine producing over 600 horsepower from the factory, it’s already a true performer.
But if you’re an enthusiast who wants to push it further – and we’re guessing you are – you’re in luck. There are BMW M8 performance upgrades that can take your M8 to the next level.
From software tuning to intake, exhaust, aero, and suspension upgrades, these five mods will help your M8 produce more power, improve throttle response, and provide sharper handling on the street or the circuit.
The Top 5 Best Upgrades for the BMW M8
1. VR Tuned ECU Flash Tune
Want the biggest bang for your buck in performance upgrades? You definitely need a great tune. The VR Tuned ECU Flash unlocks massive gains from the factory 4.4L bi-turbo V8, taking it from already fast to jaw-droppingly quick. Designed for use in racing competitions, this flash tune recalibrates engine parameters to improve power delivery, turbo response, and acceleration, all without changing any hardware.
Crank Horsepower Ratings:
- Stock Power: 625hp | 554ft/lbs
- Tuned Power: 700hp | 627ft/lbs
Whether you’re just getting started or building a full stage 2 setup, this is the most cost-effective dollar-for-horsepower BMW M8 performance upgrade you can make.
2. Akrapovic Exhaust System
An upgraded exhaust system unleashes both sound and performance, and it’s key for getting the most out of your M8. The Akrapovic exhaust improves airflow, reduces backpressure, and adds an aggressive, race-inspired tone that complements the M8’s V8 growl. And, paired with a tune, it helps change the entire vibe of this touring beast.
This system is track-tested and built to exacting standards. It features lightweight materials and OEM fitment, meaning you’re getting the best of both worlds. Whether your BMW M8 is stock or tuned, the Akrapovic system ensures your performance gains are heard and felt.
3. Eventuri Carbon Intake System
A proper cold air intake helps your turbos breathe better. A CAI brings in cooler air, promotes more efficient combustion, and can help minimize heat soak during high-speed pulls. The Eventuri Carbon Intake System was designed through in-depth testing and development, resulting in significant gains in airflow and improved turbocharger efficiency for this bi-turbo monster.

5. Body and Aero Upgrades
At Vivid Racing, we know performance isn’t just about what’s under the hood. It’s also about how your car moves through the air, its power-to-weight ratio, and its grip on the road. That’s where body and aero upgrades come into play for your M8.
A well-designed front splitter, side skirts, or rear diffuser can do more than just improve looks. They can also help improve high-speed stability, reduce lift, and even enhance cornering grip.
