Overview:
The F8x M3/M4's are an audible treat right off the showroom. Coupled with a Dinan exhaust however they become a symphony of aural delight that even the most discerning ear will find pleasing.
Dinan's Free Flow axle-back exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum backpressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to computer-controlled valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. The exhaust gasses exit through larger laser engraved polished, or ceramic black, quad tips.
Every Dinan product comes with our industry-exclusive factory matching new car bumper to bumper warranty and is designed and tested in Morgan Hill, California and can be purchased and installed at any Dinan Approved BMW dealership nationwide.
Features:
- More Power: +5 HP
- Drone abatement technologies used to reduce cabin resonance
- Enjoyably louder, sporter sound
- Quad 3.5" black ceramic coated, or polished stainless, laser engraved exhaust tips
- Computer controlled valve limits noise during low speed driving; valve opens fully during high-load conditions to allow free flow
- Stock exhaust valve actuaters are reused
- Operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-Drive settings.
- Dinan exhaust is 3 lbs lighter than stock
- Twin secondary exhaust valves with a whopping 76mm diameter, making them 45% less restrictive than the OE valves.
- 100% 304 stainless steel construction
- Uses the factory brackets and hangers for a factory-like fitment

Small But Mighty — The Best Travel Jewelry Case I’ve Ever Used
Color: Glitter White
This Hatori travel jewelry box is honestly the best little jewelry organizer I’ve ever owned. I don’t know how it works its magic, but it somehow fits so much jewelry and still looks tiny and compact. Go figure.
Size & Portability:
It’s the perfect size—small enough to toss into a suitcase, carry-on, or even a purse, but big enough to hold everything I need for a trip. Lightweight, sturdy, and it takes up almost no space.
Storage Layout:
The double-layer design is genius.
Bottom: 7 ring rolls + 3 removable compartments (I love that I can move them around depending on what I’m packing).
Top: 5 hooks and an elastic pocket to keep necklaces from tangling—YES, it actually works.
Everything stays in place, nothing gets tangled, and it looks beautifully organized when you open it. A travel miracle.
Quality:
The glittery white PU leather exterior is sturdy and cute, and the interior is lined with soft velvet that protects everything. The clasp is easy to use and feels secure—no accidental openings in your suitcase.
Why I Love It:
It’s compact, durable, organized, and honestly just adorable. Perfect for travel, but also great for keeping your everyday jewelry together in a drawer.
If you travel at all—or just like your jewelry organized—this little box is worth every penny. It packs a punch for its size.

Great travel jewelry case
Color: Black
Great colors. Good size. Easy to pack and carry. Fits a good amount of jewelry. It’s decent quality. I know there is better out there but for the value it’s great. It snaps close and I haven’t had mine accidentally come open at all. The inside is soft. My necklaces did get a little tangled inside but not too bad. I could have put them in there better. Very nice though.

Store it all!
Color: Pink
This is a compact, light weight, efficient, and sturdy/convenient way to securely store jewelry. The small compact case allows jewelry from earrings to necklaces to bracelets and rings to be all together without being tangled and/or on top of each other. I have more earrings than rings so I used the ring area to store the rest of my earrings. The tight clasp allows the lid to be fasten snuggly to the body of the case. The price was right considering what other stores were charging. I chose the pink case which is a very soft pink, as like the case, but there are other colors to choose from. The case is mobile and would stand strong in a carry on case or bag. I highly recommend this item if you are looking to organize and have your jewelry neatly and safely all in one place!

Cute and super convenient for travel
Color: Black
Really happy with this jewelry box overall. It’s compact, lightweight, and perfect for travel. The compartments are well designed for rings, earrings, and even long bracelets, which fit really nicely.
The only downside for me is the necklace section. When using multiple necklaces, they can get tangled, so it’s not the most practical part of the case. Other than that, it’s a great product for the price and looks very cute
