If you're looking to boost your BMW E46's performance, the Supersprint Left Downpipe with Metallic Catalytic Converter is worth your attention. Supersprint has been around since 1955, and they’ve really honed their craft over the years. They don’t just slap together a muffler and call it a day; they engineer a complete exhaust system that’s all about maximizing power, sound, and aesthetics.
This downpipe is crafted from T304 stainless steel, which means it’s not only durable but also resistant to corrosion. You want something that can handle the heat and the elements, right? The full kit features a 2 x Ø65mm to 2 x Ø63.5mm configuration, ensuring a smooth flow that really lets your engine breathe. Plus, it comes with a threaded bung for the oxygen sensor, so installation is straightforward and hassle-free.
What I really appreciate is the attention to detail. Supersprint isn’t just throwing parts together; they’re focused on the entire system. You can expect a noticeable improvement in power output, along with a deeper, more aggressive exhaust note that makes driving a joy. It’s designed specifically for the BMW E46, so if you’re planning a V8 S65 engine conversion, this downpipe is a perfect fit.
In a nutshell, if you want to enhance your ride with something that feels like it was made by enthusiasts for enthusiasts, this downpipe is a solid choice. It’s all about getting the best performance while keeping that classic BMW feel.

Since 1955, Supersprint has been manufacturing high-performance automotive exhaust systems, with the largest range of products in the world. Right from the start, the company’s goal was to consistently offer the highest quality materials, superior finishes, and unmatched product lineups with a keen focus on designing, researching, and supplying the best-performing exhausts all around the globe.
Many competitors choose to sell the same universal exhaust parts with only minor changes for drastically different vehicles. The consequence is a system that is not optimized for your particular vehicle and application, resulting in poorer performance than the OEM system. Supersprint, on the other hand, approaches each individual vehicle exhaust application as a custom design. By avoiding “cookie-cutter, one size fits all” exhaust systems, Supersprint is able to tailor its products to deliver consistent performance gains and incredible sound characteristics.
Trustworthy ManufacturingSupersprint’s commitment to excellence involves every stage of development. Each exhaust system has been thoroughly researched, intricately designed, and rigorously tested to ensure additional power gains and overall performance enhancements. All Supersprint designs are validated by extensive testing methods, which includes hours on the dyno, to guarantee the best possible product before it hits the market. No other race team engine testing department or car/exhaust manufacturer out there boasts the same performance evaluating experience as Supersprint.
To put it into perspective, Supersprint’s dynamometer performs well over 1,000 test runs a year on a full range of automotive brands. The brand works tirelessly to evaluate each automaker’s sports car models and all of the available engine options. What’s more, Supersprint is often called upon to provide closed-door dyno testing for some of the world’s top racing teams. This additional information helps the teams prepare for world-class rally and road racing events. The experience also provides the Supersprint staff with a database of powerband information that is unrivaled in the industry. The vital information and power figures play a large role in the design and production of each individual exhaust component and complete system that Supersprint manufactures.

The company was awarded quality certification ISO 9001 by the FAKT, which guarantees the highest standards of research, development, and production.
