KYOSTAR Catless Downpipes for Mercedes-AMG C43 GLC43 E43 M276 3.0T

The KYOSTAR Catless Downpipes are designed for Mercedes-Benz and AMG models equipped with the M276 3.0T twin-turbo V6 engine. Featuring a high-flow catless design, these downpipes reduce exhaust restriction and improve exhaust gas flow for enhanced turbo response, throttle feel, and a more aggressive exhaust character.

Manufactured for performance-focused applications, the downpipes are designed with smooth pipe routing and factory-style mounting points for a direct replacement installation. They are ideal for enthusiasts upgrading their Mercedes-AMG exhaust system, especially when combined with ECU tuning and other supporting modifications.
