Heat-shielded catless downpipes for the Mercedes-Benz M276 3.0L Bi-Turbo V6. Integrated thermal shielding dramatically reduces radiant heat transfer while allowing higher exhaust gas velocity through the turbine for quicker turbo response and reduced heat soak.
🔥 Key Benefits
- Integrated thermal shielding – Retains heat in the exhaust stream to support turbine efficiency and faster spool
- Cooler engine bay – Significantly reduces radiant heat to surrounding components and minimizes heat soak
- Catless high-flow design – Maximizes exhaust flow for a more aggressive AMG tone and sharper throttle response
- Direct bolt-on fitment – Fits OEM turbo outlets and mid-pipe with zero fabrication required
- Factory emissions components retained – Downstream catalysts remain in place for emissions compliance
