Dinan Valved Axle-Back Exhaust - 2021-2025 BMW M3/M4

The G8x M3/M4 is arguably superior in every category to its predecessor but in most, if not all, circles the biggest downfall of the platform is in the sound department. Like the F8x before it with the S55, the S58 in the current generation leaves a lot to be desired. While a step in the right direction from its forerunner the stock vocals still carry far too much rasp that do not fully articulate the refined aggressiveness typical of the brands signature performance models. Dinan corrects this weakness with a valved axle back exhaust system that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. Coupled with the optional middle exhaust / x-pipe for the platform an even louder, smoother, and fuller soundtrack is possible.

Features:

  • Maximum gains of +6 HP and +5 lb-ft of torque
  • Enjoyably louder, sportier sound
  • Drone abatement technologies used to reduce cabin resonance
  • Four, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo
  • Larger diameter piping for increased flow (76mm vs. 70mm)
  • 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)
  • Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
  • Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions
  • 100% 304 Stainless Steel construction
  • Factory-like fitment with included mounting hardware

Quality
Works very well, I also have the 11 in 1 green mac mini m4 docking hub with s 1Tb external drive installed. So f a r I'm impressed we with the quality of green products and their competitive pricing. Will be purchasing green cables in the near future. Ugreen has become my new go to company for accessories.

One cable does it all, rock solid Ethernet and great 4K output
This hub has simplified my desk setup considerably. I plug it into my MacBook and instantly have Ethernet, 4K HDMI, two USB-A ports, and 100W charging all from one connection. The Ethernet is Gigabit and the speeds are as fast as plugging directly into the router. The 4K HDMI output to my monitor is clean with no flickering. It runs slightly warm during extended use but nothing alarming. Build quality feels solid and UGREEN has been consistently reliable in my experience. Worth every penny if you need to expand a USB-C only laptop.

Nothing Special
Works as intended. I bought it mostly for the Ethernet adapter which was plug and play with the latest installation of Fedora Linux and uses an AX88179 Gigabit Ethernet chipset. The Ethernet portion does not have activity lights. A bit of a lazy omission. Port locations are smartly placed with the HDMI output and power input at the back facing one direction, and the Type A USB peripheral ports facing the other. This is great for cable routing. The single Type C port is only for power delivery. It will not work for data to connect other peripherals.

UGREEN
Very useful and compact USB-C hub. It easily expands connectivity with HDMI, USB ports, and fast charging support. The 4K HDMI output works well for presentations and streaming, and the 100W power delivery keeps devices charged without issues. Build quality feels solid, and it’s perfect for travel or daily use. Great value for the price.

Compact and useful.
It's small and light enough to fit in my bag easily. My computer uses a USB-c charger, and there's only one port, but I was able to use it for ethernet, and pass the charging through the same port. I've had issues with my computer not recognizing charging from some sources before, so this was great.
