Our racing-grade downpipes are expertly crafted from premium stainless steel, using precise and standardized bending techniques to ensure optimal performance and thrilling exhaust note. Our downpipe pricing is U.S. market guaranteed. With an unwavering commitment to both price and quality, we adhere to a "customer-first" standard, ensuring that our products exceed expectations without compromise.

Cel Delete Kit

Installing b58 catless downpipes will trigger a check engine light (CEL) due to the absence of OEM catalysts. To eliminate the CEL without a tune, we offer a CEL Delete Kit featuring O2 sensor spacers that comply with BMW’s emissions parameters, effectively removing the CEL.

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.

OPF and Non OPF

The OPF is a gasoline particulate filter integrated into the exhaust system of modern turbocharged petrol engines. Its primary function is to capture soot and fine particles produced during combustion, particularly under high-pressure direct injection, thereby reducing particulate emissions. Functionally, it is similar to a diesel DPF but specifically engineered for petrol engines.

Choose downpipe according to your car.

Easy to Install and Looks Great
Color: White, Size: 15.7 Inches
These floating shelves are a great addition to my daughter room space! They were very easy to install, and the instructions were clear and straightforward. The material feels solid and durable. I also really appreciated that the package included all the necessary hardware and materials, which made the setup even more convenient. They look great on the wall and serve their purpose perfectly. Highly recommend!

Quality Assurance Lacking
Color: White, Size: 15.7 Inches
The first set I ordered was great; super easy to install, no issues. The second set I ordered the holes on the bottom of the shelves did not match up with the holes on the bar that secures the shelves to the wall so it was impossible to attach the shelves correctly. I'm still trying to figure out a solution. TO SUMMARIZE: First set perfect; second set unusable

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
