Overview

The Mad Racing MAD-032 is a set of catless downpipes designed for BMW S58 engines. They also contribute to a more aggressive exhaust sound.
Show original supplier description
The Mad Racing MAD-032 catless downpipes are designed to upgrade the exhaust system of BMW S58-powered vehicles, specifically the M2, M3, and M4 models. By removing the stock catalytic converters, these downpipes reduce backpressure, enabling faster turbo spool and increased power output. They also enhance the vehicle's exhaust note. Constructed from 304 stainless steel with smooth bends, these downpipes are engineered for maximum airflow and are designed to minimize drone. The inclusion of a flex pipe section helps to reduce stress and unwanted vibrations. They are compatible with both right-hand drive and left-hand drive vehicles. Installation is straightforward with spot-on fitment. The MAD-032 downpipes are compatible with the 2021+ BMW M3 G80 and the 2021+ BMW M4 G82 and G83 models. Users have reported noticeable power gains and a significantly louder, more aggressive exhaust sound, with some noting the ability to hear the turbos spooling more audibly. Some users may require O2 spacers to prevent check engine lights (CEL).
