Exhaust Headers for Mercedes Benz CL500 (2000-2006) 5.0L V8

High-Flow Mid-Length Exhaust Headers for 2000-2006 Mercedes Benz CL-Class (M113 / C215)

Replaces restrictive cast iron factory manifolds with wider tubular headers to significantly reduce exhaust gas back pressure and unlock engine performance.

The Stock CL-Class Airflow Bottleneck

OEM Mercedes Benz M113 exhaust manifolds on the C215 chassis are heavily compromised by mass-production cast iron designs. The stock system utilizes narrow, unevenly paired runners that create severe bottlenecks directly at the cylinder head exhaust ports. Under heavy throttle, this generates extreme back pressure, increasing combustion chamber heat soak and suffocating top-end power potential. The factory manifolds prioritize noise suppression and compact engine bay packaging over efficient airflow dynamics, severely limiting both horsepower output and the mechanical V8 exhaust note.

The Engineering Solution

These mid-length, high-flow exhaust headers are precision-engineered to eliminate factory airflow restrictions. Constructed with wider diameter piping, the tubular design promotes superior exhaust scavenging, rapidly extracting spent gases away from the combustion chamber. By dramatically lowering back pressure, the M113 breathes freely, optimizing volumetric efficiency. Naturally aspirated V8 models typically see a 7 to 10 percent increase in horsepower and torque, while supercharged applications yield up to a 15 percent gain. Note: Custom fabrication is required; included downpipes must be welded to the existing exhaust. Specific C215 subframe clearance adjustments may be necessary. For competition off-road use only.
