Exhaust Headers for Mercedes Benz CLS55 AMG (2006-2006) 5.4L Supercharged V8

High-Flow Exhaust Headers for 2006-2006 Mercedes Benz CLS-Class (M113K / W219)

Replaces restrictive factory exhaust manifolds with wider, mid-length pipe architecture: Lowers exhaust gas back pressure and maximizes the scavenging efficiency of the supercharged M113K engine.

The Stock CLS-Class Exhaust Restriction

The OEM cast exhaust manifolds on the M113K V8 are notoriously bottlenecked, prioritizing compact packaging and noise reduction over volumetric airflow. These restrictive, log-style manifolds create massive exhaust back pressure, especially under heavy supercharged boost. This dynamic leads to severe heat soak within the engine bay, dangerously elevated exhaust gas temperatures (EGTs), and parasitic pumping losses that rob the supercharged 5.4L powertrain of its true output potential.

The Engineering Solution

These mid-length, high-flow exhaust headers utilize wide-diameter primary tubes to smooth exhaust pulsation dynamics and accelerate flow velocity. By increasing the cross-sectional area, these headers drastically reduce back pressure, allowing the supercharger to operate at peak efficiency. Installers can expect gains of up to 15 percent in horsepower and torque on supercharged applications. Notice: This is a competition-only upgrade. The header kits include downpipes that must be welded to your existing exhaust system. Due to the universal AMG multi-chassis design, expect tight clearances requiring professional adaptation, particularly around the steering shaft (W211), subframe (W220 / C215), transmission tunnel (R230), and tight engine bays (W203).
