Hey there, fellow gearheads! If you’ve been searching for a way to amp up your BMW F80 M3 or F82 M4, you’re in for a treat. We’ve been at this for over 30 years, and trust me, we know a thing or two about performance. Our latest creation, the Active Autowerke F8X rear exhaust, is all about ditching that factory sound and turning your ride into a true beast.
Let’s be real—the stock exhaust on these cars just doesn’t do them justice. It’s like putting a tuxedo on a bulldog; it just doesn’t fit. So, we rolled up our sleeves and engineered an exhaust that not only looks the part but sounds like a proper “M” car should. This isn’t just about noise; it’s about crafting a deep, throaty growl that’ll make heads turn.
And here’s the kicker: if you’re looking for something even more exciting, we’ve got the new valved version, affectionately dubbed the "Maad Maxx." Seriously, this thing flows better than ever and gives you that extra punch when you need it. We’ll have the dyno charts ready soon, but early tests show an 18+ WHP gain and over 30 LB-FT of torque compared to stock. That means quicker turbo spool and a more responsive ride. What’s not to love?
Features:
- Crafted right here in the USA
- 18+ WHP gain over stock
- 30+ LB-FT gain over stock
- Faster turbo spool for that immediate throttle response
- Rich, low rumble that’ll give you chills
- Double-canned muffler to keep resonance in check
- Test-fitted on our custom F8X Exhaust Fixture to ensure a perfect fit
- Guaranteed fit for all F80 M3 and F82 M4 models
- Comes with all the hardware you need for installation
- Flex joints to minimize vibrations and keep things smooth
Fitment:
- BMW M3 F80 (2015-2020)
- BMW M4 F82 | F83 (2015-2020)
If you’re ready to transform your ride and experience the sound and performance it was meant to have, this exhaust is the way to go. Trust me, you won’t regret it!
