Sinister Diesel 7.3L Powerstroke up pipes eliminate the slip joint in the cast merge piece which is a common location for the factory up-pipes to leak. The Sinister Diesel up pipes are constructed of stainless steel for corrosion resistance and mandrel bent for maximum flow. We have opted to get rid of the bellows in favor of a much stronger, longer lasting "double slip" flex joint. In turn, there are now, no bellows to heat fatigue and crack. It will still allow the upper and lower sections of the Up Pipes to flex and move due to heat expansion, while maintaining a 100% seal. The double slip also allows some flexibility to account for different tolerances in the motors from year to year, as well as aftermarket turbo kits. All of our up-pipe kits are fully TIG welded on a fixture as well as back-purged for the highest quality and strongest weld possible.

Kit Includes:
  • Both driver and passenger up-pipes with factory cast merge piece.
  • Hardware and Ford factory gaskets to bolt the up-pipes to the cast merge piece.
***We recommend purchasing the optional turbo O-ring seal kit with this product to ensure a leak free installation.***

Q: What is your warranty/guarantee regarding your custom slip style up pipes?
A: We do guarantee that our pipes 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. The best part is that there is no piece in it to fail, there are no longer paper thin material to fatigue and crack.
