Active Autowerke Signature F8x M3/M4 Exhaust System
Hey there, fellow car enthusiasts! If you’re looking to give your F8x M3 or M4 a serious upgrade, you might want to check out the Active Autowerke Signature Exhaust System. This isn’t just any exhaust; it’s the result of a ton of research and development aimed at striking that sweet spot between performance and sound.
Crafted from 100% 304 stainless steel and TIG welded (no cheap MIG welding here), this system is built to last and perform. The modular design means it offers a flow that can easily support power levels that far exceed what the stock S55 can handle. So, if you’ve been feeling like your stock setup is holding you back, this is the fix you’ve been waiting for.
Let’s talk about the stock setup for a second. The OEM midpipe is a dual-pipe system that doesn’t do your turbo any favors. It can make the car sound a bit rough and doesn’t help with turbo lag either. By switching to a single 3.5” pipe right after the downpipes, our exhaust promotes better scavenging and higher exhaust velocity. What does that mean for you? Quicker spool times, more power, and a much smoother exhaust note that’ll make you smile every time you hit the gas.
We’re pretty confident that this is one of the best exhausts out there. The reduced back pressure and that big single-pipe design keep the exhaust flowing smoothly throughout the system. And if you’re planning on cranking up the power with some mods, this system can handle it. It’s over-engineered to deal with the increased exhaust volume from turbo upgrades without a hitch. We didn’t just copy the OEM design; we started fresh to create something that really performs. And yes, it’s proudly made in the USA!
