BMW B48 2.0T Catless Performance Downpipe – 230i / 430i

Take your BMW's exhaust setup to the next level with the KynForm B48 2.0T Catless Performance Downpipe. Designed for selected BMW models equipped with the B48 turbocharged engine, this aftermarket downpipe is intended to provide a less restrictive exhaust path compared with the factory catalytic converter-equipped setup.

The catless design removes the factory catalytic converter, allowing exhaust gases to flow through a more direct system. This can contribute to a more aggressive exhaust note, increased turbocharger sound and a performance-focused driving experience when paired with suitable supporting modifications and tuning.

Whether you're building a modified street car or developing a more comprehensive performance setup, this downpipe is an ideal consideration for enthusiasts looking to customise their BMW's exhaust system.
