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

Excellent Goggles — Comfortable, Secure, and No Leaks
Color: Aqua
These goggles are excellent quality and were very easy to adjust. They have good suction and fit nice and tight without being uncomfortable and stayed secure the entire time I was swimming. Not much for style, but these do look pretty cool. I wore them for about an hour with no issues at all—they remained comfortable and didn’t leak, which is a huge plus. The seal held up well without leaving painful pressure marks. The included case is also a great bonus and makes storage and travel easy. Overall, a very solid pair of goggles that perform exactly as expected. Definitely recommend.

Hard Nose Bridge
Color: Blue-black
They seem like nice goggles. I would echo what others have said: The nose bridge is made of hard plastic with two little bumps on each side (conceivably to snap the lens into the nose bridge) that very well may press into your nose, making the goggles uncomfortable to wear. I would look for a pair with a soft nose bridge. I previously owned a pair of Aegend swim goggles with a soft nose bridge that I liked.

Totally worth the price!
Color: Lagoon, Style: 2 Blocks
These are great blocks! They are soft yet supportive. Used for yoga, Pilates and on the sits-bones when meditating. All purpose, perfect size, cute, calm color. I have two sets, I like them so much; one for the house and one in the gym.
