Evolution Racewerks Catted Downpipe, BMW 20i/28i F1x N20

Expert's advice:

The Evolution Racewerks N20 200-cell catted downpipe reduces exhaust backpressure, resulting in increased power and torque, improved throttle response, and faster turbo spool. Thanks to the high-flow metallic catalytic converter, exhaust gas temperatures and thermal load on the turbocharger are reduced compared to the OEM downpipe.

Manufactured from high-quality stainless steel, this downpipe replaces the original unit and offers an OEM-like fitment while maintaining compatibility with both factory and aftermarket exhaust systems.

Please note that although this downpipe is equipped with a 200-cell catalytic converter, compliance with road regulations may vary by country. ECU remapping is recommended after installation to fully optimize performance and to prevent potential check engine light warnings."
