Why long tube headers

The factory manifold is the bottleneck.

  1. The problem

    Mercedes builds its exhaust manifolds to be quiet, compact and cheap to package. On a naturally aspirated AMG V8 that chokes the engine exactly where it should be pulling hardest.

  2. What headers change

    Long, smooth primaries pull spent gas out of each cylinder instead of letting it stack up. Better scavenging means each cylinder fills with more fresh air on the next stroke.

  3. What you feel

    More power across the rev range, sharper throttle response and the V8 sound the factory muffled. Add an MBH tune and the gains roughly double.

M113 · M113K · 5.4L V8

The 55 AMG

We modelled the M113 headers in CAD around how the 5.4L actually breathes, then built them from the same hand-selected stainless as our flagship systems. Every weld is back-purged with argon, so the inside of each tube stays smooth and the exhaust keeps its speed. On the supercharged M113K cars like the CL55 we used the extra room in the engine bay for our largest, highest-flowing design.

M156 · 6.2L V8

The 63 AMG

The M156 wants to move a lot of air, so our 63 headers use a Tri-Y layout with large 2-inch primaries cut to a precise, slightly shorter length. That keeps exhaust speed up while giving the engine the volume it needs, for a strong, linear pull all the way to redline. Every set gets a multi-point inspection before it leaves Phoenix.

Header questions

Do I need a tune?

No. Headers make power on their own. A matched MBH tune is how you get the rest of it.

Do I need a mid-section?

It isn't required, but our stainless mid-section makes the install and the connection to your exhaust much easier.

Can I get them coated?

Yes. Choose the Cerakote option (+$365) on any USA-made header.
