Ceramic-Coated High-Flow Downpipes — Mercedes M276 3.0L Bi-Turbo
Precision-built ceramic-coated performance downpipes engineered for the Mercedes-Benz M276 3.0L Bi-Turbo V6. Designed to reduce exhaust restriction, improve turbo response, and manage under-hood temperatures while maintaining OEM-style fitment and reliability.
🔥 Key Benefits
- High-temperature ceramic coating: helps reduce radiant heat, protect surrounding components, and support exhaust gas velocity
- High-flow design: reduces backpressure compared to factory components
- Refined AMG sound: deeper and more pronounced under load without harshness
- OEM-style bolt-on: installs directly to factory turbo outlets and mid-pipes
- Retains downstream emissions components: factory mid-pipe catalysts remain in place
ECU calibration is recommended to optimize performance and manage emissions-related fault codes.
