The Evolution Racewerks BM-EXH038TBCAT is engineered for performance, specifically designed to replace the factory downpipe in the 2025+ BMW M5 (G90) with the S28 engine. This high flow catted downpipe addresses the common exhaust flow restrictions found in stock systems, particularly the factory catalytic converters, which can significantly hinder horsepower and torque, especially in turbocharged applications.
By replacing the primary catalytic converter with the high flow metallic unit and removing the secondary converters, the BM-EXH038TBCAT enhances exhaust flow significantly. This results in improved torque delivery and throttle response, allowing for a more engaging driving experience. The design and materials used also ensure that this downpipe can withstand higher temperatures compared to traditional ceramic options, making it a reliable choice for performance applications.
Upgrade your exhaust system with the Evolution Racewerks BM-EXH038TBCAT to experience enhanced performance and responsiveness in your 2025+ BMW M5. This downpipe is a critical component for those looking to maximize their vehicle's capabilities.
