Tubular Headers Boost Power

August 2014

Independent dyno tests of Sinister Diesel’s Tubular Headers increase horsepower and torque sooner in the RPM range, improving drivability and towing capability for 2003 to 2007 6.0L Power Stroke Super Duty trucks. Sinister Headers add 27hp and 56 ft/lbs. of torque over stock headers. When installed on a vehicle with a performance tuner, the increase is an additional 37hp and 99 ft/lbs. of torque.

Sinister Headers are manufactured for durability, built with solid stainless steel CNC flanges, and stainless steel tubing. The high flow Headers are fully TIG welded and come with an EGT bung welded onto both sides. The Headers are available in raw, ceramic and heat wrapped finishes.
