The details
Specs & details
If you have been underwhelmed by other G55 AMG exhaust options on the market, the MBH Motorsports G55 AMG Long Tube Header system is engineered to exceed your expectations. Quite simply the finest header system available for the iconic G-Wagon, this setup is designed to significantly increase the performance and capability of your heavy SUV. Whether you need more low-end grunt for towing or relentless torque for the trail and mud, these headers are the answer.
By eliminating the severe bottlenecks of the factory exhaust manifolds, our long tube headers unlock massive, usable performance, providing dyno-proven gains of upwards of 50 wheel horsepower—power you can actually feel the moment you hit the throttle.
Handcrafted USA Quality & Rugged Durability
The G-Class demands rugged reliability, and our headers are built to match. Proudly hand-fabricated in the USA, this system is constructed from heavy-duty 16-gauge T-304 American stainless steel primary tubes and mated to ultra-durable T-321 stainless steel flanges. This uncompromising build quality ensures your headers can withstand extreme towing loads, off-road abuse, mud, and intense heat cycles without warping or failing.
Key Features:
-
Massive Power Gains: Dyno-proven to add upwards of +50 wheel horsepower over restrictive stock manifolds.
-
Enhanced Utility & Torque: Unlocks the crucial low-end torque and mid-range horsepower needed for towing and off-roading.
-
USA 16-Gauge T-304 Stainless Steel: Handcrafted in the USA using premium American stainless steel for ultimate structural integrity and thermal endurance.
-
T-321 Stainless Flanges: Utilizes heavy-duty T-321 stainless steel at the engine mounting flanges to prevent warping and exhaust leaks under heavy load.
-
Precision Craftsmanship: Fully purge-welded and hand-ported to eliminate exhaust turbulence and maximize scavenging efficiency.
Compatibility:
-
Engine: Mercedes-AMG M113K 5.4L V8 Supercharged
