The most common points of failure on the Ford 6.0L Powerstroke Y-Pipe are the corrugated bellows which become heat-fatigued and crack over time causing power robbing pre-turbo exhaust leaks over time. Replacing the stock flex joints can cost you considerable time and money for a repair that will only fail again in time. But, deleting them altogether in favor of straight tubing can cause serious long term damage from heat expansion and vibration that can cause stress fractures and more exhaust leaks. On the Sinister Diesel Y-Pipes for the 6.0L Powerstroke, we have opted to get rid of the factory bellows-style joints in favor of a much stronger and longer-lasting flex joint. The new design still allows the upper and lower sections of the Y-Pipes to move due to heat expansion while maintaining a complete seal., 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., Includes:(1) Sinister Diesel Stainless Steel Y-Pipe, (1) Sinister Diesel Up-Pipe, Installation Hardware and Gasket.
