Renntech Stainless Steel Long Tube Headers - Mercedes / G 463 / G 500 (2002-2008) (NLA)

Designed, engineered and manufactured in house specifically for your Mercedes Benz. Our purge welded, ceramic coated  long tube headers feature top of the line big tube T-304 stainless steel tubing and are manufactured from the same high quality materials used on all RENNtech headers. 

We ceramic coat our headers to retain heat within them and minimize latent heat in the engine compartment and combats against thermal stress. Ceramic coating also increases exhaust-gas velocity as hotter gasses expand quicker allowing them to travel faster. By ensuring the internal header bore surfaces are smooth; turbulence is further reduced. The net result is more effective cylinder scavenging, which again offers a power increase.
