description: BMW S58 High-Flow Catted Downpipes - Yonristic Performance Product Description The BMW S58 engine is one of the most capable modern twin-turbo inline-six engines on the market, powering platforms such as the BMW G80 M3, G82/G83 M4, G87 M2, and other S58-based BMW M models. From the factory, however, the OEM downpipes are one of the most restrictive sections of the exhaust system. Positioned directly after the turbochargers, the factory catalyst assemblies are designed around emissions compliance, noise control, and global regulations rather than maximum exhaust flow. The Yonristic Performance High-Flow Catted Downpipes are designed to improve that critical section of the exhaust path. By replacing the factory catalyst assemblies with a freer-flowing catted design, the system reduces backpressure immediately after the turbochargers. This allows the turbos to spool more efficiently, improves throttle response, and gives the S58 a stronger, cleaner, and more aggressive exhaust character. Unlike fully catless downpipes, these downpipes retain catalytic converters, making them a more balanced choice for owners who want improved performance without the rawness, smell, and extreme volume of a catless setup. The system is available in two catalyst-density options depending on the customer’s goals. The 200-cell version is the more aggressive option. It offers greater flow potential, louder sound, sharper turbo response, and stronger performance support for tuned vehicles. This option is ideal for owners looking for a more noticeable upgrade in both sound and performance while still retaining a catalytic core. The 400-cell version is the more refined option. It offers improved flow over factory while maintaining a more controlled tone and a more daily-friendly character. For owners who want a cleaner upgrade, reduced harshness, and a more OEM-plus driving experience, the 400-cell option provides an excellent balance between flow, refinement, and drivability. Both versions are…
