Description

Mercedes-Benz W218 CLS400 3.5T TNEER Performance Downpipes is a vehicle-specific TNEER downpipe upgrade for the application shown in the title. Reworking this high-flow section of the exhaust can reduce restriction, support a more responsive performance setup and produce a stronger exhaust character when paired with the correct supporting hardware and calibration.

The supplied configuration must be selected to suit the vehicle’s catalyst and emissions-equipment specification. This makes it possible to choose a configuration that suits the intended road, track or competition use rather than treating every vehicle as the same.

• Vehicle-specific application: developed for Mercedes-Benz W218 CLS400 3.5T Performance Downpipes.
• Selectable configuration: confirm the required catalyst specification before ordering.
• Performance-focused flow: designed to improve the exhaust path through the downpipe section.
• Traceable listing: TNEER part reference MB-W218-CLS400-35T-DP.

Important: Downpipe changes can require compatible ECU calibration and may affect emissions compliance, warning-light operation and warranty. Catless or modified-catalyst configurations may be restricted to off-road or competition use. Professional installation is recommended.

Before ordering: Confirm the exact model year, engine, body style and OPF/GPF/catalyst specification so EA Performance can check the selected configuration against your vehicle.
