Take your BMW F97 X3M or F98 X4M to the next level with the Alpha Competition S58 Catless Downpipe. Designed to unlock the full potential of your twin-turbo S58 engine, these downpipes are built for maximum performance gains and enhanced exhaust flow. Made from high-quality 304 stainless steel, they offer excellent durability, boost turbo response, and provide a more aggressive, thrilling exhaust note.
By removing the restrictive factory catalytic converters, these downpipes significantly reduce backpressure, allowing your turbochargers to spool faster and improve throttle response. The result? More horsepower, more torque, and a driving experience that’s truly elevated. Expect gains of up to 40 bhp and 47 Nm on a stock setup, with even bigger improvements—up to 80 bhp and 135 Nm—when combined with a DME remap.
What sets the Alpha Competition downpipes apart from the competition is their smooth, mandrel-bent design, which optimizes exhaust flow for maximum efficiency and performance. This design ensures that your engine breathes easier, while other competitors may restrict airflow with necked-down sections.
Crafted with precision and built to last, these downpipes are backed by a lifetime warranty, offering long-term reliability and performance. Whether you’re hitting the track or enjoying spirited drives, the Alpha Competition S58 Catless Downpipe is a simple yet effective upgrade that brings your BMW F97 X3M or F98 X4M to life.
Ready to experience your BMW like never before? Install the Alpha Competition downpipes and feel the difference—more power, quicker spool, and a deeper exhaust tone. It’s the upgrade that will make your BMW stand out from the crowd.

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.
