Show original supplier description
The MAD-035 secondary catless downpipes from Mastery of Art & Design are engineered to be a premium exhaust system upgrade for the BMW M5 F90 and M8 F92. Crafted from durable 304 stainless steel with a polished finish, these downpipes feature smooth, mandrel-bent tubing to reduce backpressure and enhance exhaust gas flow. This design facilitates quicker turbo spooling, improved throttle response, and an increase in horsepower and torque. The package includes all necessary hardware and gaskets for a hassle-free upgrade. They are compatible with both right-hand drive and left-hand drive vehicles and include a flex section for added durability. The MAD-035 downpipes are compatible with the 4.4L S63B44T4 engine, specifically for the 2018-2023 BMW M5 F90 and the 2019-2025 BMW M8 F92 models. A key feature is their ability to provide "No Check engine light" illumination after installation. The product comes with a lifetime warranty on defects and fitment and a 90-day return period.
