E55 Long Tube Headers

Unleash the true power of your M113K engine with the MBH Motorsports E55 AMG Long Tube Headers. Widely recognized as the Gold Standard for the E55 AMG platform, our headers are the benchmark by which all others are measured.

While the market is saturated with mild steel and cheap overseas replicas offered by big-name shops, MBH Motorsports took a different path. Designed, engineered, and extensively tested in-house on a Dyno Dynamics dyno, these headers are built for discerning enthusiasts who refuse to compromise on quality, fitment, or performance.

Key Features & Product Specifications

• Massive Power Gains: Adds +45 wheel horsepower (whp) over stock as a standalone modification, and +50 whp when paired with a tune, pulley, or throttle body.

• Exclusive Horsepower Guarantee: The industry's first and only AMG header backed by a money-back power guarantee.

• Optimized Engine Efficiency: Decreases restrictive boost pressure without dropping horsepower, drastically reducing the risk of engine knock and pre-ignition.

• Advanced Tuning Flexibility: Lower boost levels allow your tuner to safely add more aggressive timing and ignition parameters to your ECU file.

• Improved Fuel Economy: Removing the highly restrictive OEM exhaust manifold improves exhaust scavenging, yielding better MPG (if you can keep your foot out of the gas).

• Premium Fitment & Compatibility: Engineered specifically for the E55 AMG, but also fits the E500 utilizing smaller connection pipes.

• Lifetime Warranty: Built to last a lifetime, guaranteed.

Proven Performance & Dyno-Tested Results

We don’t just claim horsepower numbers; we prove them. During our extensive in-house dyno testing, a stock E55 AMG equipped only with MBH Long Tube Headers consistently gained 45 whp. When you start stacking modifications—such as an upgraded supercharger pulley, larger throttle body, or an ECU tune—these headers truly shine, easily clearing the 50+ whp mark by allowing your engine to breathe.

Better Efficiency, Safer Boost

More boost doesn't always mean more power—often, it just means restriction and heat. Adding MBH Long Tube Headers relieves backpressure, which actually lowers your boost gauge reading while increasing actual horsepower. This drop in restriction lowers your engine’s operating temperatures and significantly reduces the chance of dangerous pre-ignition (knock). It is a total win-win for engine longevity and performance.

The MBH Motorsports Guarantee

We stand behind our craftsmanship like no other manufacturer in the Mercedes-Benz aftermarket space:

1. The Horsepower Guarantee: We guarantee these headers will make at least 40 wheel horsepower over stock. If they don’t, send them back for a full refund.

2. Lifetime Warranty: Your investment is fully protected against defects for as long as you own the vehicle.
