2003-2007 Ford F250 & F350 6.0L Sinister Diesel Tubular Exhaust Headers | SD-HDRS-6.0

Get More Power and Low-End Torque for your 6.0L Powerstroke

The 6.0L Powerstroke's turbocharger is key for making power, and if you want to push your aggressive 2003 to 2007 F250 or F350 build to the limit, you're going to need to get exhaust gasses over to your turbo's turbine housing quickly and with limited back pressure. Sinister Diesel's Super Duty 6.0L Exhaust Headers are to help. This pair of diesel exhaust headers feature a far more efficient and high-quality design than stock which helps your F250 or F350 produce more low-end torque, which works wonders for towing, hauling, and off-roading. These powerful exhaust headers drop right into place of your Super Duty 6.0L's factory manifolds and don't require a custom tune, making them perfect for just about any F250 or F350 Super Duty out on the road. The headers alone can add up to 27 horsepower and 39lb-ft of torque while using the factory tune, giving you power even if you want to avoid tuning.

Tubular Steel Design for Maximum Flow Efficiency

Sinister's headers for the 6.0L Powerstroke were carefully designed to improve exhaust outflow from your truck's cylinders over stock, which moves a larger volume of exhaust gasses to your turbocharger's turbine housing at higher speeds. The headers feature a tubular design with mandrel-bent primary tubes and flawless TIG welding. The flanges of each header are CNC machined for a perfect fit on your truck's engine, and the driver's side header comes standard with an EGT bung. This pair of headers are made from high-quality stainless steel and come with installation hardware, gaskets, and instructions.
