Description
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.

Guarantee:
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.

Not legal for sale or use on pollution-controlled motor vehicles anywhere in the United States. Legal ONLY for off-road competition racing vehicles and cannot be used on vehicles that are operated on public streets, roads or highways.
