The Active Autowerke BMW N63 S63 GESI G-Sport Catted Downpipes are expertly designed to maximize performance and efficiency for BMW X5M, X6M, 550i, 650i, X5, and X6 models equipped with the twin-turbo V8 S63/N63 engine. By significantly reducing exhaust back pressure, these high-flow downpipes allow the turbochargers to spool faster, resulting in quicker throttle response, increased horsepower, and improved overall performance. Constructed from handcrafted 304 stainless steel, these downpipes feature full 3-inch piping with minimal bends, ensuring unrestricted airflow and enhanced turbo efficiency. Unlike restrictive factory setups, this upgrade optimizes exhaust flow, delivering a more aggressive and refined exhaust note while maintaining durability for long-term use.
This variant includes a pair of 4.5-inch ultra high-flow GESI G-Sport catalytic converters, designed to provide superior emissions control without sacrificing performance. The GESi G-Sport Ultra High Output Catalytic Converters are EPA registered, 49-state legal, and fully OBD2 compliant, making them an ideal solution for reducing emissions while maintaining high performance. Built entirely from 304 stainless steel, including the substrate, these high-flow converters use proprietary precious metal loading technology to significantly reduce emissions, eliminate Check Engine Lights (CELs), and support engines producing between 500 and 850 horsepower. The reduced back pressure allows for maximum power gains while ensuring compliance with modern emissions regulations, making these downpipes the perfect upgrade for performance enthusiasts who want power without compromise.
Whether you’re looking for increased power, better turbo response, or an aggressive exhaust tone, these high-performance catted downpipes provide the ultimate balance of performance and emissions compliance, making them a must-have upgrade for any BMW N63 or S63 twin-turbo V8 engine.

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.
