The 2 series is the nearest embodiment of legacy BMW ideals in today's lineup. As such, in both the non-M and M trims, the series is continuously lusted after by the enthusiast community. While the G87 M2 may get the lion's share of publicity, the G42 M240i is equally as enticing and offers a robust value proposition for individuals looking to balance performance with comfort. Equipped with the latest B58 engine also found in the M340i and M440i, the M240i has performance covered in spades. Beyond the vaunted engine, the platform also borrows numerous other components from its 3 and 4 series counterparts. As such, it made sense to imbue the latest M240i with the same Dinan exhaust treatment the aforementioned models received and were heralded for -- an economical valve system with quad tips.

Quad exhaust tips have been a signature feature of the most powerful letter in the automotive sphere for quite some time. It is a hallmark of the brand that Dinan has long embraced, limiting its own quad tip usage to those M cars that already sported like tip quantity from the factory. That is until the release of the Dinan exhaust systems for the G20 M340i and G22 M440i in 2019 and now extending to the G2 M240i today. While some may scoff at the feature being implemented into a "pseudo-M," the M240i, and the B58 engine platform, are extremely potent and worthy of such a distinction. The factory valance also accommodates the four massive 102mm tips perfectly, further cementing our opinion that the quad tips were destined to be on this performance model. Being numerous and big are not the only selling points to the tips however. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. With systems available with either black ceramic coated or polished clamp-on, and laser engraved exhaust tips, there is a version that is sure to meet your individual aesthetic needs.

The use of quad tips also presented some additional challenges and fostered some innovation to the already visually impressive system constructed entirely of TIG welded and brushed T304 stainless steel. Confined to dual tips, the factory system utilizes only one exhaust valve and functions by eliminating the passenger side tip when the valve is closed, siphoning all gases through the muffler and out the driver's side tip for quieter operation. With the introduction of more pipes/tips, this methodology was not practical, or desired. In true Dinan M exhaust fashion, our talented engineering team decided that integrating a second valve to the system would garner the most favorable results in both symmetry and overall sound. The result is a system that incorporates larger 76mm tubing (vs 70mm stock) and allows freer flow through the entirety of the system but specifically to both outer pipes when the enlarged valves are open. The resulting flow and sound mimics an awe-inspiring straight pipe solution with a deeper and meatier tone, a defining element of all Dinan exhausts. In contradiction to the aggressiveness resulting from open valves, when the valves are closed, all gases are forced into the muffler for sound deadening and exit the two inner tips. Regardless of valve position, the intimate nature of the interior is retained so conversation can continue without an excessively loud drone courtesy of numerous drone abatement technologies in the can. With the Dinan exhaust equipped on the M240i you get the best of both worlds; aggressive tone/sound and civility. A combination that is paramount to any M exhaust, and now by virtue of tip count, the M240i as well. Welcome to the illustrious family.

Absolutely love these floating shelves. We bought three 30" and two 12". The quality exceeded my expectations. They feel incredibly solid, well-made, and high end. From the moment the package arrived, I could tell this company really cares about their product and their customers. Everything was packaged so elegantly and thoughtfully, with great attention to detail. Installation was straightforward, and once mounted, the shelves looked absolutely beautiful. What really stood out was the customer service. It was honestly some of the best I’ve experienced on Amazon. Super responsive, helpful, and genuinely caring. You can tell this is a company that takes pride in what they do. Highly recommend these shelves to anyone looking for something stylish, durable, and backed by amazing customer support

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues. The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area. One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure. The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly. Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect
