Evolution Racewerks Catless Downpipes, BMW M5 G90/G99 S68

Expert's advice:

The downpipes are the first section of the exhaust system after the turbochargers, where the catalytic converters are originally located. These can be replaced with downpipes featuring sport catalytic converters or with catless versions for improved airflow. The benefit of this upgrade is an increase in power and a change in exhaust sound, the car becomes louder.

These Evolution Racewerks Catless Downpipes do not include a catalytic converter, which reduces exhaust back pressure. This results in more power, significantly increased torque, and reduced thermal load on the turbocharger. The downpipes are manufactured from high-quality stainless steel, replace the original OEM downpipes, and offer perfect fitment. Please note: depending on the laws and regulations in your country, these downpipes may not be permitted for use on public roads. After installation, ECU software adjustment is required to prevent potential faults or a check engine light.
