Cel Delete Kit

The installation of catless downpipes will result in an inevitable check engine light (CEL) as the DME will detect that emissions are not being burnt up by the OEM catalyst. To remove this CEL without having to tune it out we offer the CEL Delete Kit which is comprised of O2 sensor spacers specifically calibrated to comply with BMW's parameters for a functioning catalyst. These install into the post-catalyst O2 sensor bungs, effectively removing the CEL that would otherwise appear.

Vehicles manufactured from 2019 onward are highly sensitive, and the Check Engine Light (CEL) may not always be eliminated. However, the modification may help delay its activation.

My everyday, everywhere laptop bag
Color: Brown Pu 239
This is hands-down my favorite laptop bag. It’s exactly as pictured. I use it daily and it has traveled all over the world with me. After a full year of hard, everyday use, it’s still holding up beautifully with no signs of wear. It holds a lot without feeling bulky. I’m able to carry my laptop along with content creation tools, marketing materials, chargers, and extras with ease. The two external pockets are incredibly helpful for quick-access items, and the two side drink pockets get used constantly—I often stash an umbrella or spare battery packs in them. One feature I really appreciate when traveling is the snap closure at the top. It’s a small detail, but it adds peace of mind when I’m moving through airports or traveling abroad and want an extra layer of security. It’s also surprisingly versatile style-wise. I carry it with casual outfits and professional attire, and it works with both. Trendy, practical, and thoughtfully designed. If you’re on the fence, get the bag. It’s well worth the cost in all categories. It’s reliable, well made, and clearly designed for real daily use.

Stylish and Functional, But with a Minor Quirk
Color: Brown Pu 239
I really love this PU leather backpack purse! It’s a perfect mix of style and practicality, but there’s one small design issue that keeps it from being perfect. **Pros:** - **Stylish Design:** The leather finish looks chic and goes well with any outfit. It’s versatile enough for casual outings or work. - **Spacious and Organized:** The compartments are thoughtfully designed, with plenty of space for all my essentials without feeling bulky. - **Comfortable to Wear:** The adjustable straps make it easy to carry as a backpack, and the weight distribution is great. - **Durable Material:** The PU leather feels high-quality and holds up well to daily use. **Cons:** - **Top Handles Issue:** The top handles stand straight up when I wear it as a backpack, which can look a little awkward and get in the way. It’s not a dealbreaker, but I wish they could lay flat. Overall, this backpack purse is a fantastic buy, especially for the price. If the top handle design doesn’t bother you, it’s an excellent addition to your wardrobe. Stylish, functional, and durable!

Stylish laptop backpack
Color: Black239pu
Chic backpack that holds a suprising amount of stuff. I needed a nice looking backpack for my laptop (Macbook Air 13") and accessories. It's sleek looking for work conferences and the top handles allow you to hold like a purse. I know some reviewers don't like the look, but for me, I like this feature. I have the black one and it has a nice quilted leather look. The straps have good padding and I was comfortable traveling all day. Even after walking several blocks in the rain there was no damage and everything inside stayed dry. The zipper and hardware are a good quality.

Perfect lightweight computer bag!
Color: Khaki239
Awesome lightweight bag. Very cute. Seems durable and well-made at a very good price. Has a ton of well placed pockets that keep me organized. I purchased this as a replacement for a much heavier, computer bag and this absolutely does the trick. It looked a little small when I received it, but it holds everything that I need and more. I have a 15.6 inch laptop. I highly recommend.
