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

Perfect fit and just in time. Went to 4 places and no one has this style. As good as the dealer and a third of the price. Very happy

Much higher quality then I ever expected at a great price
Size: 26"+17"+14"B(U/J Hook)
Perfect fit on my 2023 Mazda 3, they look and install exactly like the original OEM wipers but Mazda 3 can be a little tricky to install but if you search on the internet you will find plenty of helpful videos. They work really well without streaking or noise.

Excellent front wipers, rear slightly shorter than expected
Size: 22"+21"+11"(U/J Hook), Size: 22"+21"+11"(U/J Hook)
I purchased the 22", 21", and 11" windshield wiper blade set for my 2017 Jeep Grand Cherokee. The front windshield wipers (22" and 21") work perfectly—smooth, quiet, and they clean the glass very well with no streaks. Regarding the rear wiper (11"), it does work properly and gets the job done. However, it is slightly shorter than the one I previously had installed. To be fair, I did not measure my old rear wiper, but it appears the one on my vehicle was a 12" blade, even though this listing specifies 11". Overall, I’m satisfied with the performance, especially for the front wipers. Just keep in mind that the rear blade may be shorter than what you currently have installed, depending on your setup.

Nice wipers
Size: 26"+16"+12"D(U/J Hook)
I got the right ones. Checked and checked again. For my husband's subaru crosstrek. The front ones fit perfect. Installed super easy. Work nicely. Had alot of rain to check them out recently. Now the back one. Does not fit. Not sure what is wrong with it, but 2 out of 3 is good.

Finally, no more streaking and squeaking.
Size: 26"+16"(Top Lock)
Bought these a few months ago for my boyfriend’s car. It was for the purpose of replacing the OEM model that initially came with the car, as the squeaking was driving me nuts. Matching the pair to his car’s make and model here on Amazon was easy. The installation was easy as well, as they simply lock in with no difficulty for me. And they look fine as well. They’ve held up the last few months in the bitter winter here in the northeastern seaboard with no issues. No squeaking, streaking, or scraping. The material seems sturdy and of good stability, not flimsy. Definitely directing him to buy this brand again when they eventually need changed out.
