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 double slip 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. The double slip joint even allows for flexibility to accommodate aftermarket turbo kits.
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.
This product requires a 5 BUSINESS DAY LEAD TIME for fabrication. If the item is needed more quickly, please call for availability and shipping options.

We guarantee that the seams and double slip flex joints will not leak. We have spent countless hours testing, fitting and fabricating these slip joints so that they can/will expand and contract with the heat, but with this design, as they heat up, they only seal better. Without the paper-thin bellows, there is simply no place for the steel to fatigue and crack.
