If you're a BMW enthusiast, you know that performance isn't just about horsepower—it's about how your car feels on the road. Active Autowerke has been in the game for over 30 years, and they really get what makes BMWs tick. Their latest offering for the F87 M2C, F80 M3, and F82 M4 is a set of catted downpipes that are designed to take your driving experience up a notch.
These downpipes are built with a GESI G-Sport Ultra High Output Catalytic Converter, made entirely from 304 stainless steel, including the substrate. What does that mean for you? Well, first off, these babies are EPA registered and compliant in 49 states, so you won’t have to worry about any legal headaches (unless you’re in California, but that’s a different story). They’re also fully OBD2 compliant, which is perfect for any vehicle from 1996 and up.
One of the standout features here is the proprietary precious metal loading technology, which drastically cuts down emissions and helps you avoid those pesky "Check Engine Lights." You’ll notice a real difference in turbo response and spool time right from the get-go. It’s less restrictive, meaning you get a more free-flowing exhaust system that enhances both low-end and mid-range performance. Plus, higher boost levels are just a bonus!
- No Check Engine Light when using this downpipe
- Quicker turbo spool and improved response
- Less restrictive design for better flow
- Enhanced low-end and mid-range power
- GESI EPA registered and fully OBD2 compliant
- Casted upper stainless steel V-Band ensures a precise fit
- Durable enough to withstand temperatures up to 1500°F
- Operates efficiently within 9 seconds post-startup
- Easy bolt-on installation—no cutting or welding needed
- Compatible with OEM O2 sensor heat shield
- TIG welded for durability
- Ultra high flow with 400 cells per square inch catalyst
- 5-Year / 50,000 Mile Warranty on the catalytic converter
When it comes to fitment, these downpipes are tailor-made for the BMW F80 M3 and M4 from 2014 to 2018. So, if you’ve got a 2015-2019 M3 or M4, you're in luck. These downpipes are going to fit like a glove and give you the performance boost you're craving. Trust me, you’ll feel the difference as soon as you hit the road.
