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
Specs & details
Take your C55 AMG to the absolute limit. The MBH Motorsports Mercedes C55 AMG Long Tube Headers are the premier header system on the market, engineered specifically to unleash the full potential of the naturally aspirated M113 5.5-liter engine.
In fact, these are the exact same headers equipped on the world’s fastest C55 AMG, which dominates the drag strip with a 11.5-second 1/4-mile run at trap speeds crossing over 120 mph. If you want dyno-proven, track-tested performance that leaves the competition in the dust, you’ve found it.

Track-Proven, Record-Setting Power
We don't just talk about performance—we prove it where it counts. By design, our C55 AMG long tube headers maximize exhaust scavenging to pull spent exhaust gases out of the cylinder head faster. This engineering breakthrough is what propelled the quickest C55 AMG on the planet to its record-breaking 11.5-second quarter-mile time.
CAD-Designed for the M113 V8
The 5.5-liter M113 is a legendary engine, but its factory exhaust manifold is notoriously restrictive. MBH Motorsports designed these headers from the ground up using advanced CAD and flow dynamics software. By optimizing the primary tube lengths and collector dimensions specifically for the M113's displacement and firing order, we’ve unlocked horsepower gains that off-the-shelf, one-size-fits-all headers simply cannot touch.
Aerospace-Grade Weld Quality
What sets MBH Motorsports apart is our obsessive attention to detail. Every set of C55 headers is TIG welded and back-purged with Argon gas. This advanced welding technique prevents "sugar" (oxidation) on the inside of the tubes, leaving the interior walls flawlessly smooth. The result? Completely uninterrupted exhaust flow and superior structural integrity that will never crack under pressure.
