Milltek C63 AMG Secondary Catalyst Bypass

Some vehicles sport two catalysts due to their dual pipe assembly. The Secondary Catalyst Bypass pipe removes the secondary catalysst to further improve gas-flow and reduce the restrictions caused by catalysts within the exhaust system.

We believe in continuous evolution, and our research & development team work throughout the year to deliver the most in demand solutions to all your performance exhaust requirements.
