The Alpha Competition BMW G42 m240i G2X 340i 440i B58.2 Catless Downpipe is a high-performance upgrade designed to unlock more power and responsiveness from your BMW’s B58 engine. Available with or without heatshield, these downpipes replace the restrictive factory catalytic converter, allowing for better exhaust flow and giving your engine the freedom to perform at its best.
By removing the catalytic converter, the downpipes significantly improve exhaust flow, allowing the turbocharger to spool more efficiently and expel gases with less restriction. This results in noticeable gains in horsepower and torque, especially when paired with other performance modifications. The improved flow leads to quicker throttle response and a more dynamic driving experience, giving you that engaging connection to the car when accelerating or pushing the engine to its limits.
Crafted with precision from high-quality T304 stainless steel, these downpipes are built to withstand the heat and pressures of high-performance driving. The material provides a strong, lightweight design that resists corrosion and ensures long-lasting durability. The optimized flow path within the downpipe ensures maximum performance gains, making this upgrade essential for enthusiasts looking to get the most out of their BMW.
Installing these downpipes is straightforward. The Alpha Competition B58 downpipes are designed for a direct bolt-on fit, ensuring minimal downtime and hassle-free installation. The installation process requires no major modifications, and the kit comes ready to go. Keep your factory setup or pair the downpipes with upgraded hoses and clamps for added reliability.
Another benefit of the catless downpipes is the more aggressive exhaust note they produce, giving your BMW a deeper, more throaty sound. To fully optimize the performance and ensure the engine runs smoothly after the upgrade, a custom ECU tune is recommended. This tune will adjust for the changes in the exhaust flow and maximize the engine’s potential.
For those serious about improving their BMW’s performance, the Alpha Competition B58.2 Catless Downpipe is the perfect upgrade. It enhances power, improves throttle response, and delivers an exhilarating driving experience, all while maintaining durability and ease of installation. Choose the with heatshield option for additional protection against heat soak, or go without for a more straightforward, performance-focused setup.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
