Looking to Boost My BMW M8's Performance—Any Upgrade Suggestions?

Seeking Advice on BMW M8 Performance Upgrades

I’ve been considering a few performance upgrades for my BMW M8, and I’d love to hear if anyone here has experience with modifications on this power beast. I want to enhance the overall vehicle performance, especially in terms of horsepower and exhaust sound.

Here’s What I’m Thinking:

  • ECU Tune: I’ve heard that a proper ECU remap can significantly increase horsepower and torque. Anyone have recommendations for reliable tuning services?
  • Exhaust System: Looking for some depth in the sound without being too noisy. Any specific aftermarket exhausts that stand out?
  • Intake System: I’m curious about how a performance air intake might improve responsiveness. What brands have delivered results for you?
  • Suspension Upgrades: I want to improve handling for those spirited drives. Are coilovers worth it for the M8?

What to Avoid:

  • Cheap Knock-Off Parts: I want to stick to reputable brands—I’ve heard horror stories about cheap upgrades ruining performance.

Final Thoughts:

I know there’s a lot of info out there, but I’d appreciate any firsthand experiences or insights you might have. If you’ve done mods on your M8, what worked well, and what didn’t? Looking forward to your advice and thanks in advance!

Have you considered upgrading to an aftermarket exhaust system? It can enhance both performance and sound. Brands like Akrapovic have great options for the M8!

Definitely! I went with a Remus system, and I love the deep growl it gives while improving airflow. Just keep in mind it can be a bit loud for daily driving.

For performance tuning, a tuning chip like the Dinan options can give you a significant boost in horsepower and torque. Just ensure you have a compatible model!

I’ve heard good things about Dinan too! Do these chips affect warranty coverage at all?

You might want to look into suspension upgrades as well. Brands like H&R offer lowering springs that can improve handling, but keep in mind it may affect ride comfort.

Great suggestion! I’m curious if anyone’s tried coilovers for the M8? I’m looking for something adjustable for track days.

Coilovers would be an excellent choice for track performance. Just ensure they’re street-friendly if you’re not on the track all the time. What’s your ride height preference?

Don’t forget about a cold air intake! They can improve airflow and are generally easier to install than other upgrades. Has anyone compared brands?

Good point! I installed a K&N intake, and I’ve noticed better throttle response. Just watch out for the installation—it’s a bit tricky.

If you’re looking for a balance, a software tune from a reputable shop combined with an exhaust can give a robust power increase without drastic modifications.

I’m a bit hesitant about tuning chips because of the risk of driving issues. Anyone had negative experiences?

I had a rough experience with one; it threw off my engine management. Just ensure you go with a reputable brand and have it installed by a pro.

A little humor never hurts! Why did the BMW M8 break up with its girlfriend? It found someone with better performance!

I recently installed a tune on my M8, and it really boosted performance! Just make sure to do plenty of research on the tuning software you choose.

That sounds awesome! Did you do the installation yourself or have a professional do it? I’ve been considering a tune too but want to make sure I don’t mess it up.

If you’re not comfortable with the installation, I’d recommend going to a professional. There are definitely challenges, especially with wiring and software integration.

I agree with kelly31. I tried a DIY exhaust install once and regretted it! Good tools make a big difference, but some things are best left to the pros.

Yeah, for an exhaust upgrade, I’d suggest professional help unless you’re really confident. What tools did you use for your install, lloydgary?
