SS304 High-Flow Catless Downpipes with Integrated Heat Shields for LHD Mercedes M276 3.0L Twin-Turbo Models
Designed for compatible Mercedes-Benz C43 AMG, E43 AMG, C400 and C450 models powered by the M276 3.0L twin-turbo V6, these catless performance downpipes replace the restrictive factory catalytic converter sections with a significantly freer-flowing exhaust path. This version is specifically designed for Left-Hand Drive (LHD) vehicles without OPF/GPF.
Manufactured from high-quality SS304 stainless steel, the downpipes are engineered to withstand the extreme exhaust temperatures generated directly after the twin turbochargers while providing excellent corrosion resistance, strength and long-term durability. The catless construction removes the restrictive factory primary catalytic converter sections to maximise post-turbo exhaust flow.
Integrated metal heat shields surround the downpipe sections to help manage radiant exhaust temperatures within the tightly packaged M276 engine bay. The shielding helps keep heat concentrated within the exhaust system and away from surrounding wiring, hoses and engine-bay components.
The vehicle-specific pipe routing is designed around the factory M276 turbocharger and exhaust connection points. Original oxygen sensors and applicable OEM components should be transferred during installation where required. Installation hardware is included, and professional installation is strongly recommended due to the turbocharger connections, sensor locations and restricted engine-bay access.

Important Notice:
This product is intended for off-road, track and motorsport use only. Removal of factory catalytic converters may not comply with emissions or public road-use regulations in your country or region.
These downpipes are designed specifically for Left-Hand Drive (LHD), Non-OPF / Non-GPF vehicles. They are not suitable for Right-Hand Drive vehicles unless fitment has been independently confirmed.
Installation of catless downpipes may trigger a Check Engine Light (CEL) due to changes in catalytic converter and oxygen sensor monitoring. Appropriate ECU software or calibration may be required depending on the vehicle setup.
It is the customer's responsibility to confirm all applicable local emissions, inspection and road-use regulations before purchasing or installing this product.
