Quick Ship SKU #: SD-YPIPE-6_0-EGR-RC-Main Sinister Diesel Stainless Steel Up-Pipes 03-07 Ford 6.0L Powerstroke

Is your 6.0L Ford Powerstroke riddled with exhaust leaks and poor performance? Chances are your up-pipes are cracked and leaking. Sinister Diesel has a solution for you! The Sinister Diesel Stainless Steel Up-Pipes. These up-pipes 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 Up-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.

SINISTER GUARANTEE:

• Sinister guarantees that the seams and double slip flex joints will not leak. They 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.
