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

Super Gentle, Super Effective — My Skin Finally Feels Normal Again
Size: 19 Fl Oz (Pack of 1)
I’ve tried a bunch of face washes over the years, and most of them left my skin tight, dry, or weirdly irritated. I decided to switch to the CeraVe Hydrating Facial Cleanser after hearing so many good things about it — and honestly, I wish I had bought it sooner.
First off, the texture is different from your typical foaming cleanser. It’s more like a creamy gel, which I actually ended up loving. It doesn’t strip your skin or leave that squeaky, dry feeling. Instead, it cleans without ever making my skin feel like it’s being punished. When I rinse it off, my face feels soft, calm, and hydrated — like I actually still have moisture in my skin.
The ingredients are what make this thing so legit: hyaluronic acid for hydration, ceramides to repair the skin barrier, and glycerin to lock everything in. It’s fragrance-free, gentle, and literally approved by the National Eczema Association, so you know it’s made for sensitive skin.
After using it daily, my skin went from dry and flaky to smooth and balanced. No breakouts, no redness, no random patches of irritation. It’s just a simple, dependable cleanser that does exactly what it’s supposed to do. If you wear sunscreen or light makeup, it removes it without any issues — and without needing two harsh cleanses.
If you’re someone with normal to dry skin, sensitive skin, or you just want a face wash that won’t mess up your moisture barrier, this is hands-down one of the best options out there. It’s gentle, effective, and honestly makes washing your face feel like part of taking care of yourself rather than a chore.
Highly recommend — it’s one of those products you buy once and immediately understand why everyone loves it.

I highly recommend it for anyone looking to improve their skin.

Perfect for Sensitive Skin Without Feeling Heavy
Size: 3 Fl Oz (Pack of 1)
I have very sensitive skin and finding a facial moisturizer that hydrates well without causing irritation can be a challenge. This one has been fantastic. It feels lightweight going on but still gives enough moisture that my skin stays soft and comfortable all day. No strong fragrance, no burning, no breakouts, just simple and effective skincare.
I also really like that it layers well under makeup and doesn’t leave my face feeling greasy or sticky. The ceramides and hyaluronic acid make my skin feel healthier and more balanced overall. Vanicream continues to be one of the few brands my skin consistently tolerates well. I’ve already repurchased this and will keep using it.

Good for sensitive skin, zero fragrance, leaves skin soft and moisturized!
Size: 3 Fl Oz (Pack of 1)
I got this to go along with my Vanicream sensitive skin cleanser, and I'm very happy with it! It is a little more liquidy than cream-like, but it absorbs into skin well and leaves it feeling soft and moisturized. Great for sensitive skin and completely free of fragrance, with a shorter ingredient list that gives me more peace of mind. Very pleased with this, try it!
