The details
The Mercedes CLK55 AMG is a true enthusiast's car, but to unlock its full potential, it requires an exhaust system engineered without compromise. MBH Motorsports CLK55 AMG Long Tube Headers are widely recognized as the absolute best headers available on the market for this platform today. Designed utilizing advanced CAD modeling and flow dynamics software specifically tailored to the breathing characteristics of the naturally aspirated M113 5.4L AMG engine, these headers deliver staggering horsepower gains far beyond any competing system.
We refuse to cut corners on any product we manufacture, and the CLK55 AMG system is no exception. Built from the same top-tier, hand-selected USA stainless steel found in all of our premium flagship headers, this system undergoes rigorous quality inspections throughout the entire fabrication process.
To ensure absolute maximum performance, every single weld is fully back-purged with Argon gas. This crucial fabrication technique prevents internal oxidation and guarantees perfectly smooth inner wall transitions. The result is ultra-efficient exhaust velocity, completely unhindered exhaust flow, and superior weld strength that will last a lifetime.
Unrivaled Power Gains: 60+ hp 60+ tq with tuning. Engineered to outflow and outperform any other header system available for the CLK55 AMG platform.
Advanced CAD & Flow Dynamics: Purpose-built using sophisticated computational flow modeling specifically calibrated for the M113 AMG V8.
Argon Back-Purged Welds: Guarantees flawlessly smooth internal pipe transitions for uninterrupted exhaust gas velocity and maximum structural integrity.
USA Premium Stainless Steel: Handcrafted using the highest-quality American stainless steel for ultimate thermal endurance and durability.
Uncompromising Quality Control: Subjected to rigorous, multi-point inspections to ensure perfect fitment and elite craftsmanship.
Engine: Mercedes-AMG M113 5.4L V8 (Naturally Aspirated)
Chassis: Mercedes-Benz CLK55 AMG
