Race Headers are for Non-US or racing vehicles only.


These produce a pressure wave that is too strong for the factory muffler (it will crack under heavy use). You have the option to choose Dundon Lifetime Muffler (in quiet or loud) or an Inconel Megaphone Center Muffler Delete "CrackPipe™" to complement the headers.


Due to the material properties of Inconel, our lifetime warranty does NOT apply to Inconel Race Headers. These parts come with a 12 month limited warranty against material and manufacturer defects. This includes, but is not limited to, cracking and weld integrity. The warranty does NOT cover misuse, installation errors or physical damage (like a crash). Any warranty claims are subject to a physical inspection and will be repaired or replaced at the discretion of Dundon Motorsports.
