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, black ceramic coated 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

Good Tool
Size: One Size, Style: Bottle Opener
This thing is great at opening bottles, and it has a Klein handle. Perfect for the electrician in your life, even if that's yourself. I had to knock off a star because the handle is not quite as good as other Klein tools. The plastic is not as clear. The TIP-IDENT bottlecap marking is off-center and not fully printed. The bottle opener sticks out at a slight angle. This does not affect the performance, but it does detract from the novelty somewhat.

expands work space effectively
Initially it was a bit challenging to set up as I was not fortunate enough to have assistance (the instructions tell you that you need two people for part of the installation process). I also had to play around with placement a bit as my available installation space was extremely limited and neither of the listed/'suggested mounting situations worked for me; however, with some head-scratching and debating with myself, I finally figured how to make it work how and where I needed it it, and all was good!! It functions well, and holds adequate weight, and looks really good with the light lacquer finish...the only thing I will say to a potential buyer is to make sure you have room to walk past it easily when its closed down because it still sticks out a few inches even when closed down...overall, very happy with this item and would purchase again.

Is there a little expensive but they work great to add counter space. My wife liked it so much I bought a second one.
