Fabtech-Performance is happy to offer these Handcrafted Mercedes MBHE63 AMG Long tube headers. Our E63 AMG long tube headers are built in the “Tri-Y” design. We do this to take advantage of the E63 AMG equipped with the M156 6.3 liter, naturally aspirated engine. These headers are able to build low end torque, along with fantastic horsepower gains throughout the entire RPM range. With help for our advanced scavenging design.
