CLS63 Long Tube Headers

The naturally aspirated 6.2L M156 V8 powering the Mercedes CLS63 AMG is an absolute masterpiece of engineering, but restrictive factory exhaust manifolds choke exhaust velocity and leave massive power trapped in the heads. MBH Motorsports CLS63 AMG Long Tube Headers are engineered from the ground up to eliminate that bottleneck, extracting spent exhaust pulses with unmatched efficiency and unleashing the true capability of the M156 platform.

Built on an advanced Tri-Y (4-into-2-into-1) configuration, these headers deliver scavenging performance that standard designs cannot replicate. By utilizing large 2-inch primary runners engineered at a calculated, optimized length, this system satisfies the high-volume exhaust demands of the 6.2L engine without causing velocity drop. The result is broad, unrelenting power and torque across the entire rev range. MBH CLS63 headers have powered some of the fastest M156 builds in the world, supporting setups exceeding 600+ wheel horsepower.

Handcrafted American Quality & Zero-Failure

Every set of MBH Motorsports headers is proudly hand-fabricated in the USA from premium 16-gauge T-304 American stainless steel to withstand extreme track abuse and aggressive heat cycling. Built to an uncompromising standard, our long tube headers boast an unblemished record: to date, we have never had a single header fail. Each set undergoes a rigorous multi-point inspection before leaving our facility, verifying flawless weld penetration, structural consistency, and clean, deburred header ports for smooth internal flow.

Key Features:

• Massive Power gains: 120+ hp 90+ tq with tuning. Dyno-tested and track-proven on the world’s most powerful CLS63 builds exceeding 650 wheel horsepower.

• Advanced Tri-Y Scavenging: Maximizes exhaust gas extraction out of the cylinder head ports for broad horsepower and torque gains across the entire RPM curve.

• Tuned 2-Inch Primaries: Sized specifically to match the displacement and flow needs of the M156 6.2L V8 without sacrificing low-end velocity.

• 16-Gauge T-304 US Stainless Steel: Handcrafted in the USA using heavy-duty American stainless steel for ultimate thermal endurance and corrosion resistance.

• Flawless Quality Control: Meticulously inspected for weld penetration, structural integrity, and smooth internal port transitions.

• Exotic V8 Acoustic Profile: Frees up the deep, ferocious, naturally aspirated AMG exhaust crackle while keeping cabin resonance manageable.
