Looking to elevate the acoustics of your X3 M40i / X4 M40i with an exhaust system that not only offers a much-improved sound while retaining the the flexibility associated with valves, but also raises the eye appeal beyond the mundane? Look no further than the Dinan valved cat-back to meet all your needs… and then some!
The full cat-back requires no cutting and utilizes factory mounting locations that allow the Dinan exhaust system to be a straightforward and painless install. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipe, the upgraded system is also a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. The most glaring change being the replacement of the OEM dual slip tips in favor of an M-inspired quad tip configuration. Despite the limited room, Dinan was determined to offer four individually functioning pathways/tips and not lessen the representation with Y-tips or other gimmickry. The result is a proper quad setup furnished with cavity covering 3.75-inch (95mm) tips in either black ceramic or polished stainless ensuring the system can be appreciated even before it is heard.
While looks are important, the auditory advantages are what any enthusiast is truly after with an exhaust system, and the Dinan offering for the G01/G02 M40i platform delivers in spades. For not only aural enhancement via the elimination of the central collector/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer flowing single pipe system. This pathway feeds into a Helmholtz equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM's) to rowdy when in it (high RPM's), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle. No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.
Features:
- Maximum gains of +6 HP and +5 lb-ft of torque
- Enjoyably louder, sportier sound w/ a delightful octave drop
- Drone abatement technologies used to reduce cabin resonance

- 7-pounds lighter than the stock system (60-pounds vs. Dinan: 53-pounds)

- Factory valve functionality retained; refined or rowdy from the same exhaust
- Direct bolt-on w/ no cutting or welding required

Psyllium Husk Caps – Easy, Effective Fiber for Digestive Health
Size: 500 Count (Pack of 1)
If you’re looking to boost your fiber intake without having to deal with mixing powders, NOW Foods Psyllium Husk Caps are a convenient solution. Each capsule contains 500 mg of psyllium husk, a natural soluble fiber that supports digestive health and helps keep you regular. With 500 capsules per bottle, this is a great value, especially for anyone who wants to incorporate fiber into their daily routine easily.
Benefits and Effectiveness:
Psyllium husk is known for its ability to absorb water and form a gel-like substance that moves through your digestive system, helping to support regularity and bowel health. These capsules make it easy to get the benefits of psyllium without the gritty texture of powders. The soluble fiber also promotes satiety, so you may find it helpful if you’re looking to manage hunger or maintain a balanced diet.
Easy to Take:
With the capsule form, you don’t need to measure or mix anything. Just take a few capsules with a full glass of water, and you’re all set. Be sure to drink plenty of water with each dose, as psyllium absorbs water and needs enough fluid to be effective.
Quality and Assurance:
NOW Foods is a trusted brand, and these psyllium husk caps are Non-GMO Project Verified, which means they meet strict quality standards. The capsules are also vegetarian, making them a great choice for those following plant-based diets.
Pros:
Convenient capsule form—no mixing or measuring needed
Supports regularity and digestive health
Non-GMO and vegetarian-friendly
High-quality, affordable option for daily fiber intake
Cons:
The capsules are a bit large, so if you have difficulty swallowing pills, keep this in mind
It’s important to drink plenty of water with these, which may be challenging for some users
If you’re new to fiber supplements, start with a lower dose to avoid potential digestive discomfort
Pro Tip:
Start with a small dose if you’re new to fiber supplements—try one or two capsules and gradually increase to avoid bloating or discomfort as your body adjusts to the added fiber.
Bottom Line:
NOW Foods Psyllium Husk Caps offer a simple, effective way to increase your fiber intake and support digestive health. They’re convenient, high-quality, and come in a generous 500-capsule bottle, making them a great addition to your daily wellness routine.
