PPE 316119511 High-Flow Up-Pipes | 2011-2014 Ford 6.7L Powerstroke Super Duty (Pickup & Chassis Cab)

Factory up-pipes on the 6.7L Power Stroke are a known weak point — they crack, leak, and restrict exhaust flow over time. The PPE 316119511 High-Flow Up-Pipes solve these issues with a direct-fit, high-performance upgrade built for durability and better flow.

Constructed from premium 304 stainless steel and fully TIG welded, these up-pipes deliver the strength and corrosion resistance your diesel deserves. The 2-inch diameter design is 50% larger than stock, creating an unrestricted path for exhaust gases and reducing back pressure by up to 65%. The result is improved turbo spool, better efficiency, and stronger torque delivery — especially noticeable on tuned or deleted trucks.

Internally sleeved bellows provide excellent flexibility while withstanding extreme heat and pressure. These up-pipes are fully compatible with your factory EGT and EBP sensors, so no wiring or sensor modifications are required. Stainless steel gaskets are included for a complete, leak-free installation.
