Spools like a different car
Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

The details
MBH Motorsports is proud to offer the ultimate exhaust upgrade for the formidable Mercedes CLK63 AMG Black Series. Engineered specifically to maximize the output of the naturally aspirated M156 6.2L V8, these long tube headers are crafted 100% from premium heavy-duty stainless steel to deliver uncompromised performance on the race track.
Unlike standard designs, our headers utilize an advanced Tri-Y configuration for unparalleled exhaust scavenging efficiency. By featuring large 2-inch primary tubes set at a precision-calculated, slightly shorter length, we perfectly satisfy the high-volume breathing needs of the M156 engine without sacrificing exhaust velocity. This exact balance ensures your Black Series never leaves power on the table, resulting in a massive, linear power band throughout the entire RPM range.
These headers are built to handle extreme abuse. In fact, our M156 header systems have propelled some of the most powerful 63 AMGs in the world to well over 600 wheel horsepower. We back this elite performance with uncompromising quality control; every single header undergoes a rigorous multi-point inspection—evaluating everything from flawless weld consistency to absolute port cleanliness—before it ever leaves our facility. To date, we have never had a single long tube header fail.
Advanced Tri-Y Design: Delivers superior exhaust scavenging efficiency compared to traditional long tube configurations.
Optimized 2-Inch Primaries: Custom-calculated lengths satisfy high-volume airflow needs to maximize horsepower without sacrificing torque.
