Exhaust Headers for Mercedes Benz CLS500 (2006-2006) 5.0L V8

High-Flow Mid-Length Exhaust Headers for 2006-2006 Mercedes Benz CLS-Class (M113 / C219)

Replaces the restrictive factory exhaust manifolds with wider, high-flowing pipes to significantly reduce back pressure and increase volumetric efficiency.

The Stock CLS-Class Exhaust Manifold Bottleneck

The factory exhaust manifolds on the 2006 Mercedes-Benz CLS500 were designed primarily for production efficiency and sound suppression, heavily restricting the M113 V8 engine's exhaust flow. The OEM cast iron log-style manifolds create severe turbulence and exhaust gas back pressure at higher RPMs. This physical bottleneck prevents effective cylinder scavenging, trapping hot exhaust gases inside the combustion chamber. The result is increased heat soak, retarded ignition timing under load, and an artificially muted exhaust note that masks the true mechanical character of the 5.0L displacement.

The Engineering Solution

Transitioning to these mid-length, high-flow exhaust headers resolves the factory flow limitations by utilizing wider primary pipes and smoother flow transitions. By optimizing exhaust gas velocity and scavenging effects, this header kit drastically reduces back pressure, allowing the M113 to breathe freely. Mechanics will note that a naturally aspirated V8 will typically gain 7 to 10 percent in horsepower and torque, while supercharged variants can see up to a 15 percent increase. The kit includes the necessary downpipes, which must be professionally welded to your existing exhaust system. Note: This is a competition-use-only product, strictly intended for off-road applications.
