Comparison
Compared With The Alternatives
| Factory up-pipe and Y-pipe | The stock assembly is designed for emissions compliance and lower noise, this one increases flow with a 2.25 inch bore |
|---|---|
| Mild steel aftermarket X-pipe | Mild steel is cheaper but rusts at the flange; stainless steel lasts longer in harsh environments |
| Universal cut-to-fit pipe | A universal pipe requires welding and fitting; this one bolts on with included hardware |
Installation
Use Guide
- Confirm the truck is a 2003-2007 Ford F-250 or F-350 Super Duty with 6.6L Powerstroke and matches the listed submodels
- Let the engine cool completely before removing the factory up-pipe and Y-pipe
- Replace the factory gasket with the included one to prevent leaks
- Install all hardware and torque bolts in a crisscross pattern to maintain sealing face flatness
- Recheck torque after the first heat cycle to ensure no loosening occurs
