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
Specs & details
Unleash the full potential of your high-performance flagship sedan with MBH Motorsports Mercedes S63 AMG Long Tube Headers. Specifically engineered to eliminate the restrictive factory exhaust manifolds on the M156 naturally aspirated V8, this header system dramatically optimizes exhaust scavenging, accelerates exhaust gas velocity, and maximizes flow efficiency.
As a standalone modification on an otherwise stock vehicle, you can expect dyno-proven gains of 40+ wheel horsepower and 40+ ft-lbs of wheel torque, delivering an immediate improvement in throttle response, low-end torque, and high-RPM pull.
Handcrafted American Craftsmanship
Every set of MBH S63 AMG headers is proudly designed, built, and inspected in the USA using heavy-duty, 16-gauge T-304 American stainless steel. We hand-select our tubing to ensure superior wall thickness, structural integrity, and maximum resistance to thermal fatigue. Throughout the fabrication process, each header undergoes continuous, multi-stage inspections to guarantee motorsport-grade weld quality, flawless fitment, and unrivaled durability under aggressive driving conditions.
Key Features:
-
Dyno-Proven Performance: Delivers +40 WHP and +40 WTQ or more over stock manifolds as a standalone bolt-on upgrade.
-
Heavy-Duty USA Stainless Steel: Built from premium 16-gauge T-304 American stainless steel to prevent cracking, warping, and corrosion under extreme heat cycles.
-
Hand-Selected Tubing: Fabricated exclusively from top-grade materials, continuously inspected at every stage of production for zero-defect quality.
-
Advanced Scavenging Design: Eliminates exhaust backpressure to produce a broader powerband, faster revving, and a deep, aggressive AMG exhaust note.
