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

Buy it you won’t regret it
This is the best toy ever! My Rottie loves it and can entertain herself for quite a while. The unpredictability of its bounce when tossed keeps her guessing and moving getting lots of energy out. Great for tug as well, or roll it on flat surfaces, it’ll go forever! She love the squeaky too

Best dog toy ever!
We saw someone with one of these at the dog park and thought that it would be perfect for our male Boxer, Buster. He has torn up just about every toy we’ve gotten him and this thing seemed really durable and really fun. Buster absolutely loves this toy! It is definitely the most expensive dog toy I’ve ever bought, but we’ve had it for months, he plays hard with it every day, and it is perfectly intact still! I wish I had known about it sooner so I wouldn’t have wasted money on Toys that he destroyed quickly. If you don’t like squeaky toys this may not be for you because once they figure out how to get it to squeak, you’ll be hearing it often. The nice thing is it doesn’t squeak without a lot of effort and it takes a strong dog to get it going. It doesn’t squeak when it’s just rolling around so that’s a plus. It is big and heavy though so be careful not to trip over it! Fortunately, it’s easy to spot with the bright color on one side. Highly recommended!

Durable, Fun, Best Toy Ever for My Spoiled Rotten Rottweiler
This is one of the best toys EVER for our 107 lb male Rottweiler. We have had the Med/Large size for over a year and it has remained Sam’s favorite toy and proven extremely durable. We play fetch and toss/catch with it in the yard and he throws it in the air, pounces on it and makes it squeak like prey. BTW some reviews say their toys don’t squeak; I am guessing those people have the wrong kind of dog for this toy. I can’t make it squeak with my hands, but my Rottie’s powerful jaws have no problem. It’s ideal as a toy for a big, powerful dog when all other toys have fallen apart. I just got Sam the Large/XL size and he was absolutely delighted with it!

Not Boerboel proof
I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately. She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole. It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.
