BD Diesel is back with another improvement for all you Dodge Ram owners out there. On the docket this time is their heavy duty 6.7L exhaust manifold replacement that they claim is “better than stock.” The 2-piece manifold, which is made from high silicon ductile iron that stands up to extreme temperatures, allows for heat growth without cracking or leaking. The open throat and larger porting enhance your turbo response and reduces turbo drive pressure and cylinder temperatures. BD also has manifolds with a T4 mount and gasket kits available for purchase. For more information visit www.dieselperformance.com or call 1-800-887-5030.
