Sinister Diesel 6.0L Powerstroke Y-Pipes are made from stainless steel tubing and solid stainless steel CNC flanges. All seams are TIG welded on a fixture for precise fitment tolerances and then back-purged for the highest quality and strongest welds possible. This Y-Pipe is designed to fit the 2003-2007 6.0L Powerstroke Super Duty and Excursion and is available in Raw Stainless, Ceramic Coated, or Wrapped finishes for extra protection, durability, and a clean and stylish appearance.
The product requires the use of an EGR delete and RACE tuning as there is no provision for the factory EGR system.
