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 now with the release of the Dinan axle back exhaust system for the G20 M340i.
While some may scoff at the feature being implemented into a "pseudo-M," the M340i, 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 gasses 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 M340i you get the best of both worlds; aggressive tone/sound and civility. A combination that is a paramount to any M exhaust, and now by virtue of tip count, the M340i. Welcome to the illustrious family.

Noticeable Comfort and Joint Support
Size: 60 Count (Pack of 1)
The Ceylon Cinnamon Capsules – Extra Strength have been a great addition to my daily routine, and I’m genuinely impressed with the results. After consistent use, I noticed reduced knee pain, and the swelling in my knees has also gone down, which has made a real difference in day-to-day comfort and mobility. The capsules are easy to swallow and gentle on the stomach, which I really appreciate. Knowing this is Ceylon cinnamon—often considered higher quality than standard cinnamon—gave me confidence in the product, and it definitely feels well-made and thoughtfully formulated. Over time, I found that stiffness decreased and movement felt easier, especially after being on my feet for long periods. While results can vary from person to person, this supplement worked well for me and supported my overall joint comfort without any unwanted side effects. Overall, this is a high-quality cinnamon supplement that delivered real, noticeable benefits for my knees. If you’re looking for a natural supplement to support comfort and reduce inflammation-related discomfort, these extra-strength Ceylon Cinnamon capsules are absolutely worth trying.
