BMW N55 Downpipe with High-Flow Race Cat (Up to July 2013 Production) - ESBM105KITB
Enhance your BMW N55 engine's performance with the Xforce Stainless Steel Downpipe. This high-performance upgrade is specifically designed for N55-powered vehicles equipped with a pneumatic wastegate and a production date up to July 2013. Featuring a large 3.9" pipe size that tapers to 3" with OEM flange compatibility, it seamlessly integrates with your factory cat-back exhaust while significantly reducing backpressure.
The inclusion of a 200-cell metallic race catalytic converter ensures increased exhaust flow for faster turbo spool and improved throttle response, while effectively minimizing exhaust gas smells compared to catless alternatives. With O2 sensor ports in the standard locations and a 105mm turbo V-band flange, this downpipe is engineered for a precise fit and straightforward installation.

- 304 Stainless Steel: High-grade non-polished construction for superior heat resistance and durability.
- 200-Cell Metallic High-Flow Cat: Optimized for performance without the restriction of a factory ceramic converter.
- Large 3.9" to 3" Design: Maximizes initial exhaust volume at the turbo exit before transitioning to the 3" mid-section.
- 105mm Turbo V-Band: Precise fitment for early N55 turbocharger housings.
- OEM Compatibility: Includes a 3" to twin OEM-size adapter pipe to suit factory cat-back systems.
- Fitting Kit Included: Comes with the necessary hardware to assist with a secure installation.

Perfect Keto-Friendly Gum, Clean Ingredients & Great Flavor!
Flavor Name: Spearmint, Size: 55 Count (Pack of 1), Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
I’ve tried so many sugar-free gums, and this is by far the best option for anyone following a keto or strict carnivore lifestyle. It’s aspartame-free, has clean ingredients, and doesn’t leave that artificial aftertaste that most gums have. The spearmint flavor is fresh and long-lasting, and I love that it helps satisfy cravings without adding sugar or unnecessary carbs.
The texture stays soft longer than other brands, and the resealable bag is super convenient for keeping in the car, gym bag, or at work. If you’re looking for a healthier gum that fits perfectly into a low-carb, keto, or carnivore-focused routine, this is definitely the one to buy. Four stars only because the flavor only lasts about a minute.

Good alternative to traditional gums- no aspartame no artificial coloring.
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
Love this gum, no aspartame, no artificial coloring and good taste, you get used to chewing it for a long time, the taste goes away little faster than traditional gums but I don't care

Great Xylitol Chewing Gum!
Flavor Name: Spearmint, Size: 55 Count (Pack of 3), Flavor Name: Spearmint, Size: 55 Count (Pack of 3)
This review is for PUR Gum | Aspartame Free Chewing Gum | 100% Xylitol | Natural Spearmint Flavored Gum, 55 Pieces (Pack of 3). I got 2 of the 3-pack at the time because it was cheaper to do so than to get a 6-pack. Of course, the next day the 6-pack was cheaper lol. Anyway, this is great xylitol gum and not overly expensive like Zellie’s. I take 2 (which is one serving meaning 2g of xylitol) after “most” meals because it’s supposed to be good for my oral health. I chew one piece at a time for a couple minutes to prolong the sweet flavor instead of popping both into my mouth together. I like chewing these because they don’t harden up like some gums do. They stay soft throughout and I often forget and chew them for 15-20 minutes at a time. Anyway, I did the math and compared the PUR gum to other 100% xylitol gums out there and this one was a clear winner to me for the same benefits. I would totally recommend this gum and I like that it’s aspartame free! I’d give it a 5.0/5.0 - 03/20/2026.

Great taste but cannot use
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
First time trying for dental care. Really enjoy the taste only drawback taste doesn’t last long. However, it’s better than other sugar substitutes which my stomach does not like.
Glad I signed up for the three pack sub. Great product! Recommend.
May 16, 2026 Update: Unfortunately I cannot use this product after the initial trial every time I chew on these i experience stomach issues so the three pack I purchased will need to find someone that can use them or throw out.

Powerful lasting peppermint flavor & the xylitol fights plaque!
Flavor Name: Spearmint, Size: 55 Count (Pack of 6)
The gum has a powerful peppermint taste – very refreshing. The flavor lasts a long time. The main reason that I bought this gum is because it has 100% xylitol. Xylitol helps fight plaque buildup. I have only had the product one day, so I can't say that it works, but I read many reports before I bought the gum that xylitol is excellent for fighting plaque buildup. It also has no sugar. It's vegan and it has only five calories per two pieces. I have so far only chewed one piece at a time. One piece seems plenty for me. I've read that people need from six to ten grams of xylitol per day to effectively fight plaque. So, this gum needs to be chewed accordingly. Many people chew after every time they eat. I am happy with this purchase.
