MAD Secondary Cat Delete Pipes for BMW M2 G87, M3 G80, M4 G82 (S58 Engine)

This installation requires medium difficulty and is suitable for experienced DIYers with a good understanding of exhaust systems and access to basic tools like jack stands, a socket set, and potentially a torque wrench. Before starting, ensure the exhaust system has cooled completely to prevent burns and allow for easier handling of components. Pay close attention to the clearance of the factory heat shields during removal and reinstallation, and carefully transfer the O2 sensors to the new pipes, ensuring they are properly seated and torqued to prevent exhaust leaks.
